Image Processing Toolbox 2.2
Support for 16-bit Image Data
Most of the functions in the toolbox have been rewritten to add support for processing 16-bit image data. Chapter 1, "Introduction," of the Image Processing Toolbox User's Guide discusses working withuint16 images.
Data Type Conversion
The new functionim2uint16 converts uint8 and double images to uint16. Chapter 1, "Introduction," of the Image Processing Toolbox User's Guide discusses using im2uint16. (See "Converting the Data Types of Images.")
Improved Speed
The following functions have been improved for faster performance:bwfill, bwselect, bwlabel, dilate, erode, histeq, imresize, imrotate, ordfilt2, medfilt2, and im2uint8.
New Border-Handling Options
New border-handling options have been added tomedfilt2 and ordfilt2.
Image-Related MATLAB 5.3 Changes
Several enhancements to MATLAB 5.3 have a direct impact on the feature set and usability of the Image Processing Toolbox 2.2:uint8, int8, uint16, int16, uint32, int32). When working with these data types, you can use relational operators (<,>,==,~=), logical operators (&,|,~), bit functions, and the following functions: any, all, find, min, max, permute, transpose, sum, and reshape.
Bug Fixes
Version 2.2 of the Image Processing Toolbox also incorporates several bug fixes. Typeinfo images at the command prompt for a detailed list of bug fixes.
