The executables are for the pc windows operating system in 32 bit or 64 bit flavor. It is highly recommended to use 64 bit execs because 32 bit execs can only address 4 gigabytes of memory and are not updated anymore. So, if your machine is 64 bit, please use the 64 bit archives, not the 32 bit archives. The programs were developed on a linux machine using Qt for the graphical interface. The port to windows was done rather painlessly thanks to the MinGW compiling environment.

Given an executable (for example, DMAG5), the number (5 for DMAG5) used after the acronym (DMAG for DMAG5) is not a version number. For example, in the DMAG line of software, DMAG, DMAG2, DMAG3, DMAG4, DMAG5, DMAG6, and DMAG7 have very little to do with each other. In particular, DMAG7 is certainly not better than the rest.

The executables without GUI (Graphical User Interface) are run via a .bat file (batch file). When you unzip any of the archives containing GUI-less executables, there will be a manual for the program of interest called *_manual.pdf (where * is the name of the program) which explains how to use the program. There will also be a directory called *_test (where * is the name of the program) that contains a sample test case which can be run directly by double-clicking on the batch file after having made sure the path to the .exe executable in the batch file is correct. Typically, to run any of the GUI-less executables, one would create a directory which contains the input images, copy the batch file (*.bat) and the input file (*_input.txt) from the *_test directory, edit the batch file so that the path to the .exe executable is correct, possibly edit the input file to modify the parameters, and then double-click on the batch file to launch the program of interest. Personally, to edit a file, I use a program called Notepad++ but any other text editor can be used. If you are experiencing problems running the GUI-less executables, please send me you batch file (*.bat file) and input file (*_input.txt) where * is the name of the program you want to use.

For some executables, the image size doesn't matter too much, in other words, you can use pixel heavy stuff but, in general, it's better to take it easy on the image size and start with images that are relatively small (under two mega pixels for instance). If it looks like the executable is not completely hogging the machine, then you can try using larger images. If you really don't want to reduce the size of the images, you can make use of the downsampling factor that's available in some of the executables.

Recommendations on what to use depending on what you are looking for:

Two-view epipolar rectification:
- Use ER9b to rectify the images. Note that the input two views may be completely misaligned. The quality of the rectification process is given by the mean vertical disparity error (it's usually close to perfect if below 0.5 pixels) written out to the output. If ER9b appears to be too aggressive (large zooming effect and/or large white framing areas), please use ER9c. I strongly recommend using ER9b or ER9c prior to generating depth maps. ER9b and ER9c give the min and max disparities in the output (please, use the 2nd line) which are used in the input of most automatic depth map generators on offer here.

Generation of depth map from two views:
- To get the depth map or the depth maps (left and right), I have implemented (in chronological order): DMAG, DMAG2 (please, use downsampling if images are large), DMAG3 (please, use downsampling if images are large), DMAG5, DMAG6 (please, use downsampling if images are large), and DMAG7. In most cases, I recommend using DMAG5 or DMAG5b followed by DMAG9b. If the stereo baseline (distance between the lenses) is small, I would actually recommend using DMAG5b over DMAG5. Check A Qualitative Comparison of Selected Automatic Depth Map Generators for a link to an academic looking paper that attempts to compare DMAG2, DMAG5, DMAG6, and DMAG7. Check Depth Map Generation using Optical Flow for an in-depth look at DMAG. Check Depth Map Generation using Graph Cuts for an in-depth look at DMAG3. To improve depth map quality (whatever the origin), I (highly) recommend using DMAG9b.

Generation of intermediate synthetic views (tweeners) between the left and right images:
- Use FSG6 to get the intermediate frames. Input is the left image, left depth map, right image, and right depth map. Make sure that the right depth map is such that foreground is white and background is black (just like the left depth map). If the right depth map comes from a depth map generator that produces two depth maps (left and right), it will need to be color inverted before using FSG6. If you have only have one reference image and one depth map or if you want to increase the stereo effect of a stereo pair, you can use FSG4 to get synthetic frames on either side of the reference image. I believe it's better if the object boundaries in the depth map are crisp (use the symmetric nearest neighbor noise reducer under Filters->Enhance in gimp). I believe it's a good idea to grow the lighter areas in the depth map (use the dilate option under Filters->Generic in gimp). As an alternative to FSG4, I recommend using StereoPhoto Maker. Once you have loaded your image and depth map, click on Edit->Depth Map->Create Multiple Images from 2D+Depth Map and you will be able get your synthetic images (there is even a preview mode that will show an animated gif of the synthetic images).

Generation of depth map from multiple views:
- Use SfM10 (Structure from Motion) to get the nvm file and then DMAG8b to get the depth map. I don't recommend using DMAG8 which is based on DMAG7. Make sure the viewpoints are not too different, in other words, make sure the camera is not moved too much between shots. I think it's better to get the 3D scene (with MVS10) than to get a depth map from multiple views.

3D scene reconstruction from multiple views:
- Use SfM10 (Structure from Motion) to get the nvm file and then MVS10 (Multi-View Stereo) to get the dense 3D reconstruction. The main output is a point cloud representing the 3D scene in ply format. This process is referred to as photogrammetry.

2D to 3D image conversion:
- Use DMAG4, DMAG11, or the3dconverter2 (preferred). DMAG4 and DMAG11 relies on a so-called sparse depth map where depth clues are given by making a few brush strokes for the different "known" depths. DMAG4 uses a so-called "edge image" so that the depths can not bleed across object boundaries (use a low beta, like beta = 10, to get very smooth depths within the edges defined by the "edge image"). To know more about DMAG4, check 2D to 3D Image Conversion using DMAG4. DMAG11 may be used as an alternative to DMAG4 with very similar results but you can't use an "edge image". If you are well versed in gimp (in particular, gimp paths), you can use the3dconverter2 for the ultimate experience in 2d to 3d image conversion. The3dconverter2 relies on gimp paths to drive the depth map densification process although you can certainly also scribble depth clues just like with DMAG4 and DMAG11. I personally recommend using the3dconverter2 for all your 2d to 3d conversion needs.

Edge-preserving smoothing:
- Not sure it's needed since the depth map generators on offer here all have some kind of edge-preserving safeguards built in. If you have depth maps with outliers (tiny specks at the wrong depths), EPS9 is good at removing them. To smooth depth maps while preserving object boundaries, you can use EPS2, EPS5, or EPS7. You can see them in action in 3D Photos - Reindeer. I personally tend to prefer EPS2 which is a "true" (as opposed to approximated) bilateral filter. Personally, I do not use any of them as I prefer to use DMAG9b for all my depth map improvement needs.

Depth map improvement:
- To improve the quality of any depth map, DMAG9b is what you want to use. It is a very powerful tool, much more potent than a mere edge preserving smoother. DMAG9b is more a depth map "improver" than a depth map generator. To see DMAG9b in action against EPS2, EPS5, and EPS7, check 3D Photos - Reindeer. For more info about DMAG9b, consult Depth Map Improvement Using The Fast Bilateral Solver. If you want to improve a depth map semi-manually, I would recommend using either DMAG4 or DMAG11. For more info on how to improve depth maps with DMAG4, check Case Study - How to improve depth map quality with DMAG9b and DMAG4.

Generation of an animated 3d gif (smooth wiggle/wobble not to be confused with the migraine inducing two-view wiggle) from a reference image and depth map:
- Use Wiggle Maker to get the animated gif. As an alternative, you can also use depthy.me but the depth map will need to be inverted (in depthy.me, black is foreground and white is background).

Depth map visualization:
- Use Depth Player to display the 3d scene given a reference image and a depth map. As an alternative, you can also use Depth Map Viewer to visualize depth maps in 3d.

What follows is the complete list of all the executables that you can download. The executables which are grouped into archives (in the rar format) are hosted on dropbox. I strongly recommend not to use the 32-bit archives as they are not updated.

From now on, I will not support 32 bit any longer as it is safe to say that nobody uses (or should use) Windows xp anymore. Everything is going to be 64 bit. Also, I will not bother with a graphical interface any longer. There is no point having a graphical interface when any parameter that is needed can be read from a file. Also, it is plain easier for me not to have to worry about Qt on Linux (where I develop everything) and Windows. Within each archive and for each piece of software, there is a manual (for example, dmag7_manual.pdf for dmag7) which I strongly recommend you read and a test directory (for example, dmag7_test for dmag7) where you can check that the piece of software you are interesting in runs correctly on your machine. If you are having any problems, send me an email and I will help you.

If you have any questions, want to give me some feedback/suggestions, or just want to let me know that you are using my software (successfully I hope), send me an email (ugocapetodifrancia3d gmail com), tweet at me (ugocapeto3d), or leave a comment somewhere. The more feedback (positive or negative) I get, the more motivation I have to keep going, so don't hesitate to contact me.

When the manual says to put the correct path to the executable in the .bat file, the way to get the proper path is as follows:
- using the file explorer, go to the directory where you have extracted the archive (where the executables are),
- click on the folder symbol to the left of the current "symbolic" path,
- copy/paste that path (should already be selected) into the .bat file.

    1. You flip (horizontally) the right image, that becomes your new image1. You flip the left image, that becomes image2. You give that to DMAG5 with the exact same parameters. You flip the depth map that's obtained, it's your right depth map. it's explained here in more details: http://3dstereophoto.blogspot.com/2014/11/3d-photos-pipes.html

    2. It is a method that extracts depth maps, from a single photograph, the photograph requirement is that count with depth on field. finally a depth is extracted after calculating the amount of blurring at the edges of objects. more distant objects have a greater blur. I think, is really good implementation for 2d to 3d vídeos; Pretty than best to something looks like depth propagación.
      Are some papers in internet, if do you want try search"depth from defocus single image"

    1. DMAG9 is used differently than DMAG4 as it doesn't have a graphical user interface. There's a file called dmag9_manual.pdf that explains how to use DMAG9. By the way, DMAG4 is probably superior to DMAG9 but it is slower. So you don't really need DMAG9 if you already have DMAG4.

    Replies
    1. The 64 bit exectuables are not graphical so they need to be run differently from the 32 bit executables that are all graphical. Say, you want to run dmag7 on a set of images in a directory on your computer. Make sure you follow the directions given in the file called dmag7_manual.pdf. The simplest way is to look at the directory called dmag7_test and copy the .bat file to the directory where your images are and make sure the path to the executable is correct. You also need to copy the input file called dmag7_input.txt. If you still have problems, send me your .bat file and your input file.

      Delete
    2. To run dmag7, then you simply double click on the .bat file.

  21. Hi! Amazing softwares! I Have been playing with each Depth Map Generator for a while now. WHich depth map do you feel gives the best results for Stereo Pairs?

    I have had the most success with DMAG5?

    Thanks!

    ReplyDelete
    Replies
    1. dmag5 works for most stereo pairs. if the edges are not crisp, you can use dmag9b to improve depth map. in some cases, you may have to use a different depth map generator like dmag3, for instance. it depends.

      Delete
    2. Thanks Ugo! I will check out DMAG9 and 3.

      I am having an issue with the ground and sky not being captured for the depth map?

      I believe the ground is not matching as it gets a little bit warped toward the bottom of the image?

      But the sky is mostly blue so I am unsure why it isnt just pure black?
      Any ideas?

      THanks!

      Delete
    3. Areas with no texture have unknown depths, so you can end up with whatever depth for those. if you're planning on creating lenticulars or wobbles/wiggles, it really doesn't matter if the depth is wrong for those areas. Anyways, try to increase the radius and see if that helps. also, make sure the stereo pair is properly aligned/rectified.

      Delete
    4. Thanks for the speedy response Ugo,

      The issue is I am trying to create geometry from the depth map, so the sky will look extremely wrong if it has random depths?

      Is there a way that I can make the generator recognize that the sky has no depth thus render it black?

  23. Hi, can I use your tools to create a anaglyph 3D picture from a depth map and a picture?

    ReplyDelete
    Replies
    1. You can use FSG4 to create either a left or right image with reference image being at the center (you use either the lefty image + center image or center image + right image to make the anaglyph). Then use stereophotomaker to actually make the anaglyph. You can also use https://sourceforge.net/projects/two2three/ to create the anaglyph directly from image and depth map. The differences will be in the quality of the inpainting.

  25. Ugo, since many years I am using your software. And I'm really surprised that you are always working on it and provide us with updates. But sometimes I've got the problem that your tools doesn't accept the (sparse) depthmaps created in Gimp because of their transparence. I found out that the default value for the alpha-threshhold that is in my Gimp 127 sometimes doesn't work and I have to reduce it to 100 to make it working. Can you suggest a value that always works? It happens, too that in DMAG4 the red background - as a rule indication for the right alpha-value - appears and the tool refuses to work even so. No problem, if you wish some proves in the forme of files. Thank you and best wishes from Germany.

  28. Greetings Ugo, my name is Justin...I've a question to ask you. Can DMAG generate good depth maps from stereo pairs that are created using the converged / toed-in setup? As you likely know, the converged / toed-in setup has some problems unique to it. These are depth plane curvature, keystone distortion...and a "baked in" convergence point fixed always at the center of the 3d image. The convergence point always has no parallax. About depth map generation, I am a beginner...so I am using DMAG1 because of it's simpler user interface. Anyway, I hope you can help...thanks Ugo.

    1. Depth map generation in the case of a stereo pair assumes no toe-in. It's usually a good idea to rectify the stereo pair prior to using the depth map using ER9b. I also suggest using DMAG5 or DMAG6 (possibly followed by DMAG9b) to get depth maps from stereo pairs.

  30. Hello

    I have following problem:

    For a project we would like to measure the distance of an moving object to a pair of cameras. Is there a software not only producing nice 3D images, but actual 3D information (eg as text/dxf file?), on how far an object is away.

    There is access to the site, so we can make reference measurements of distances and angles and the like from the surrounding scene. Basically the data come from HD/FHD movie cameras, but a full motion analyses is not intended.

    Accuracy does not need to be very high, in the range of 10 -20 cm would be cool.

    Best and thanks a lot for the help

    1. From the disparity, you can get the actual distance to the object if you know the geometry of the camera setup (focal length and baseline). it's a very simple linear equation, something like Z (depth) = fB/d where B is the baseline and d the disparity. As far as software, usually, they just compute the disparity map and you'll have to get the actual depths yourself (that's what pcm11 does: creating point cloud in 3d space from depth map).

  32. Hi,
    I've got problems with DMAG8 and 10 creating a depthmap with SFM. No matter, if using a larger number of images or just 2 or 3. I downloaded your examples (pump), but in all cases I get an error e.g. "Can't find camera corresponding to ref image!" or the output is an image without content.
    When using SFM as standalone I always get the known error about the initialization pair. In most cases the workaround described in your help files is succesful, but df8 doesn't accept them, nevertheless. Years ago I had got acceptable results testing sfm, so I am sure and I know that I don't make any mistake in handling the tool. Working on Win10 64.

    1. Try to have a look at what the program prints at the beginning of the run. It will print the parameters it's reading from the input file. If you see something weird printed out for a given parameter, then there's something wrong with that line in the input file. My guess is that there is something wrong with one of the file names in the input file. Most likely the name of the output depth map. Make sure there's no space in the name or weird symbols. If you still have problems, send me your input file and the 2 images (reference image and input depth map).

    1. how to use df2: you just pick a point in the foreground, click on it in the left image then click on it in the right image, the disparity should appear in the main window at the bottom. Do the same thing for a point in the background.

      instead of using df2, you can use er9b or er9c to get the min and max disparities automatically. Look for the line in the output that says min/max disparities. There should be 2 lines with that information. Use the second line.

    1. I am pretty sure you can combine image and depth map into a lens blur image (maybe with exiftool or depthy.me) and then use that viewer as is. Otherwise, yeah, that viewer could be modified to load an image + depth map instead of a lens blur image.

    2. Ok, I have just tried combining an image and a depth mao using depthy.me and it works just fine. Once you have uploaded the 2 files, click on the "Share" button and "Save as JPG". That will get you a lens blur image. Make sure the depth map is such that black is near and white is far. Then you can use https://www.clicktorelease.com/code/depth-player/ to visualize the scene and possibly export to sketchfab.

    4. Gordon: I am gonna try to adapt the depth viewer so that you can load the reference image and the depth map directly, without having to combine them first in depthy.me. Do you use the "export to sketchfab" feature or do you just use the "export to obj" and then load that in sketchfab? If you want, reply by sending me an email, that might be easier to communicate.

    1. Probably dmag5b. Before that though, make sure the 2 images are well aligned/rectified. If the 2 images are not aligned, using Stereophotomaker is probably the easier to use for alignment purposes. Maybe go into Edit->Preferences->Adjustment and check the "Better Precision (slow)" before you align in SPM.

    ReplyDelete
    Replies
    1. The only thing i can suggest is to try improve the depth map quality using a joint bilateral filter like dmag9b. This should make the object boundaries more crisp. Play with "sample rate spatial" and "lambda" to control how much the depth map is allowed to be changed. The lower the sample rate spatial and the lower lambda, the less the depth map will be changed.

      Delete
    2. Also, if you want to edit the depth map semi-automatically in case the errors are large, I suggest uisng the3dconverter2 (see this video https://youtu.be/nv1T-0jGQ_I). You can also edit the depth map manually in SPM if you want.

If you are still having problems, send me an email.

    2. Is you stereo pair a left and right image? meaning, the 2 pictures are different viewpoints of the same scene. Just want to make sure you are not trying to get a depth map from 2 identical images.
