CGFStereoChecker

This plugin highlights the most divergent pixels of a stereo pair. A number of pixels from the right eye, to the left and right of a given coordinate, are subtracted from the corresponding left eye pixel. The least significant value is put into the output image. The lesser the value of a pixel in the output image, the less artifacts will be present in that area when watching in 3D. Bright areas show that the stereo pair is always divergent in that area, regardless of a viewing angle in 3D.
