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 (also outputs min and max disparities needed by automatic depth map generators). 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). If ER9b appears to be too aggressive (large zooming effect and/or large white framing areas) and the views are not too misaligned to begin with, use StereoPhoto Maker's auto-alignment feature and get the min and max disparities with DF2. I strongly recommend using ER9b prior to generating depth maps although I understand having a lot of rotation in the images can be a problem.

Generation of depth map from two views:
- To get depth map or the depth maps, I have implemented (in chronological order): DMAG (followed by DMAG9b if you don't like fuzzy object borders), DMAG2 (use downsampling if images are large), DMAG3 (use downsampling if images are large), DMAG5, DMAG6 (use downsampling if images are large), or DMAG7. I recommend using DMAG5 for most stereo pairs because it's fast and it usually gives good results. For small stereo baseline, DMAG5b should be used instead of 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, you may want to post-process the depth map(s) with 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 or its big brother FSG11 to get synthetic frames on either side of the reference image.

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. Computing a depth map in the multi-view case is not recommended. It makes much more sense to compute the dense 3D reconstruction instead.

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.

2D to 3D image conversion:
- Use DMAG4 to get the depth map in a semi-automatic manner. DMAG9 or DMAG11 may be used as an alternative with very similar results. To know more about DMAG4, check 2D to 3D Image Conversion using DMAG4.

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 temd to prefer EPS2 which is a "true" (as opposed to approximated) bilateral filter.

Depth map improvement:
- To improve the quality of any depth map, DMAG9b can be used. 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.

Generation of an animated 3d gif (smooth wiggle not to be confused with the migraine inducing two-view wiggle) from a reference image and depth map:
- Use wigglemaker to get the animated gif.

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.

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.

    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.

    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.

    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?

    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.

    ReplyDelete
    Replies
    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.

  29. 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).

  30. Is there some way I can run this on a Linux machine, without using virtual machines? Do you have a linux compatible export?

    1. No, sorry, there's no linux version of the software that's available for download.
