Function Enhancement
improved and is now a private function, rather than a
subfunction.
imhist No longer causes a docked figure window to become undocked.
imrotate Now correctly rotates N-dimensional arrays, where N is
greater than 3. In previous releases, imrotate would accept
N-D arrays but only return a 3-D array.
normxcorr2 Now always returns real values. In previous releases,
due to roundoff error, some sets of input data caused the
normxcorr2 function to return a complex valued matrix of
correlation coefficients.
pixval Now works correctly with binary images.
rgb2ind Now returns a correct output image when called with the
syntax
rgb2ind(rgb,n,'nodither')
where n is greater than 256.
Fixes to Image Processing Toolbox Deployment Issues
• Performance issues that occurred when deploying compiled image processing toolbox
functions that call IPPL routines have been fixed.
• Running compiled versions of imtool and some of the other modular interactive tools
no longer generates the following warning messages about classes not being cleared:
Warning: Objects of graphics.linkprop class exist - not clearing
this class or any of its super-classes.
Warning: An object instance still exists. Use the objectdirectory
command to see a count of existing instances.
New Directory Needed
The Image Processing Toolbox software now requires the following new directory on the
MATLAB path:
toolbox\shared\imageslib
