User`s guide

13-3
In previous releases, if you changed the preferences with the iptsetpref command,
these changes would revert to the default setting when you finished a MATLAB session.
Now, if you change preferences, these changes will remain intact from one MATLAB
session to the next.
New imcolormaptool Function That Opens Choose Colormap Tool
The new function imcolormaptool opens the Choose Colormap tool. The Choose Colormap
tool allows you to interactively change the colormap of a displayed image. You can also
access the tool from the Tools menu of the Image Tool, as in previous releases.
End Point and Branch Point Detection Now Possible
bwmorph now detects end points and branch points in binary images.
nitfread Now Allows Image Subregion Selection
The nitfread function now includes a PixelRegion parameter that returns a subimage
as specified by row and column vectors.
Compatibility Considerations
From R2007a to R2008b, the nitfread function returned uint8 data for images with 1-
bit data. Now nitfread returns logical data for images with 1-bit data. If you want
this function to behave as it did in the past, enter the following:
imdata = uint8(nitfread(filename));
Support for Intel IPP on Mac
In previous releases, the Image Processing Toolbox leveraged the Intel Integrated
Performance Primitives (Intel IPP) Library on 32- and 64-bit Linux
®
and Windows
®
platforms. Now Intel IPP-use has been extended to the Mac.
