Image Processing Toolbox

New Features in Version 2.2

Version 2.2 offers the following new features: 16-bit image processing (most functions); speed optimization of many functions, including bwfill, bwselect, bwlabel, dilate, erode, histeq, imresize, imrotate, ordfilt2, medfilt2, and im2uint8; new border-padding options for medfilt2 and ordfilt2; and a new function, im2uint16.

In addition, some of the new features and changes in MATLAB 5.3 (Release 11) are relevant to the operation of the Image Processing Toolbox 2.2. Relevant changes in MATLAB 5.3 include: improved support for integer types (uint8, int8, uint16, int16, uint32, and int32); support for two new file formats, PNG and HDF-EOS; 16-bit image display; and 16-bit TIFF file I/O.

Updates to Earlier Versions

Version 2.1 offered the following new features: inverse Radon transform; interactive pixel value display including distance between two pixels; advanced feature measurement; Canny edge detection; YCbCr color space support; easier data precision conversion; and a new feature for the bwfill function--the ability to automatically detect and fill holes in objects.

Version 2.0 offered the following new features: support for 8-bit image data; support for manipulating RGB and multiframe images as multidimensional arrays; optimization of some 1.0 functions; and many new functions.

For a detailed description of the changes in Versions 2.0, 2.1, and 2.2, see the Release 11 New Features document.
