Fancy cuboid visualization. Extracts cuboids of given size from the array I at specified locations, using cuboid_extract. It then displays a fancy visualiztion of the cuboids. Only works if I is MxN or MxNxK (2 or 3 dimensional data). Tends to work well only if not too much overlap between cuboids (otherwise V is very dark). INPUTS I - d dimension array cuboids_rs - the dimensions of the cuboids to find (d x 1) subs - subscricts of max locations (n x d) show - [optional] figure to use for display (no display if == 0) OUTPUTS V - color version of I with each cuboid being a different color Imasked - I with everything blocked out except regions belonging to cuboids See also CUBOID_EXTRACT, CUBOID_DISPLAY_STV
