** The functions entropyfilt, rangefilt, and stdfilt were completely
incorrect and have now been fixed.
** In function regionprops, "Perimeter" was changed to be compatible
with Matlab, and "PerimterOld" was added.
** In function regionprops, properties "ConvexHull", "ConvexImage",
"ConvexArea", and "Solidity" were added.
** In function bwfill, the parameter connectivity was changed. In
previous versions, the parameter referred to background
connectivity but now refers to the foreground connectivity. This
backwards incompatible changes was done for Matlab compatibility.
Effectively, to obtain the same results as in previous versions
use a value of 8 instead of 4, and a value of 4 instead of 8 (the
default was 8).
** grayslice now expects argument V to be a vector with the actual
values used to perform threshold. Previously it expected values
in the [0 1] range which would be adjust to the correct type
internally. This change was done for Matlab compatibility (which
does the same despite their documentation stating otherwise).
Other small changes were done to be Matlab compatible in multiple
** The function operation "thin" in bwmorph was changed to be Matlab
compatible. The previous implementation, based on the book by
W. K. Pratt, is available under the name "thin-pratt".
** imcast now also converts images to logical type.
** wiener2 is now able to handle images with arbitrary number of
** Other functions that have been changed for smaller bugfixes,
increased Matlab compatibility, or performance:
