Frame Sequence Generator 2 (FSG2)

Frame Sequence Generator 2 (FSG2) generates synthesized intermediate frames given a left image (image 1), a disparity/depth map, and the min and max disparities (needed to compute the actual disparity from the depth map). The basic idea is, for each frame, to shift the pixels in the left image according to the disparity map. This frame will have "holes" (disoccluded pixels) which are filled by an ultra simplistic in-painting algorithm. When the foreground of an image stays stationary and the background shifts (to the right), disoccluded areas are created which can be filled, in a very simplistic manner, by copying the rightmost visible (not disoccluded) pixel. For a more sophisticated method, check out Frame Sequence Generator 4 (FSG4)..

If imageL.xxx is the left image (image 1), the frames generated will be named frame1.xxx, frame2.xxx, etc. The last frame corresponds to the right image. Animated gifs or lenticular prints (see Lenticular Printing - Interlacing with SuperFlip) can be made with imageL.xxx, frame1.xxx, frame2.xxx, etc (don't use the actual right image). The program automatically creates an animated gif of those images after generating and saving the frames.

The disparity/depth map should be a grayscale image where white indicates closest foreground object and black indicates furthest background object. The darkest value in the depthmap corresponds to the minimum disparity and the brightest value corresponds to the maximum disparity. The disparity/depth map doesn't need to come from any of my programs.

Here's an example:

Left image of the "Art" stereo pair (part of 2005 Middlebury dataset).

Depth/disparity map.

Disoccluded areas ("holes") which result from the shifting of the reference image (left image) to get the "right" image (which you get when you ask to generate just 1 frame).

Pseudo-right image obtained with FSG2 (you get the "right" image when you generate just 1 frame).

The windows executable (guaranteed to be virus free) is available for free via the 3D Software Page. Please, refer to the 'Help->About' page in the actual program for how to use it.
