Random-Dot Stereograms
Coherence-based stereo utilizes simple disparity estimators which work
directly with the image intensities. Obviously, an intensity-based algorithm
might have difficulties with images composed only of black and white pixels,
like classical random-dot stereograms. Here's the result of a calculation
with such an image pair (see also here for a
sparse RDS):

Another difficult test for stereo algorithms is the repetitive structure
found in many in SIRDS. Here's an example
of a disparity map calculated from such an image:
