Frame Sequence Generator 6 (FSG6)

Frame Sequence Generator 6 (FSG6) interpolates views between a left image and a right image using the left and right disparity/depth maps. FSG6 relies on backward mapping/warping as explained in View Interpolation (forward mapping/warping and backward mapping/warping).

The input to FSG6 is:
- left image,
- right image,
- left depth map,
- right depth map,
- minimum disparity and maximum disparity (the ones you used to generate the left depth map), and
- the number of frames needed.

The number of frames includes the left and right images. As an example, if the number of frames requested is 3 and the file type of image 1 (left image) is png, the interpolated views will be named frame0.png, frame1.png, and frame2.png. The first frame (in this case, frame0.png) is always a copy of image 1 (left image) and the last frame (in this case, frame3.png) is always a copy of image 2 (right frame).

What follows is for depth map generators that only generate the left depth map:

To generate the right depth map after having generated the left depth map (using any automatic depth map generator that only outputs a left depth map), all you have to do is flip the right image horizontally (that's gonna be your new image 1), flip the left image horizontally (that's gonna be your new image 2), and give the two new images to the depth map generator keeping the minimum and maximum disparities unchanged (and any other parameter unchanged as well). The resulting depth map is the right depth map once it has been flipped horizontally. Flipping an image horizontally is quite easy to do in Photoshop or The Gimp.

In contrast, if your favorite depth map generator generates both depth maps in one shot like DMAG5 or DMAG6, then you don't have to do any of the flipping mentioned above. All you need to do is color invert the right depth map so that the foreground is white and the background is black, just like for the left depth map.

The interpolated views can be used to make an animated 3d gif (wiggle) or to make a lenticular (via interlacing).

If you want to see FSG6 in action, you may want to have a look at 3D Photos - Pumpkins since I give an illustrated example that starts with a stereo pair and ends with a wiggle gif containing the intermediate images computed by FS6.
