releases, see the Release 12 Release Notes.
•
fspecial — Fixed incorrect normalization for the Gaussian filter option.
•
improfile — Fixed an occasional indexing problem caused by round-off
error.

rgb2ind — Fixed a problem that caused rgb2ind to produce bad results for
very large images.
•Functions that operate on binary input images now treat
NaNs in a consistent
manner. When an input array that is expected to be a binary image contains
NaN values, the NaN value is always treated as 1.
