Released: 01 Sep 2007
 

Version 6.0, part of Release 2007b, includes the following enhancements:

• New interactive tool (implay) for viewing MATLAB movies, videos, or image sequences
• New programmable GUI tools for interactive placement and manipulation of regions of interest (ROI)
• Image Tool includes interactive cropping, contrast enhancement that can modify image data, and ability to save changed images to files
• New demosaic function to convert Bayer pattern encoded images to truecolor RGB images
• New impyramid function to create a multiresolution Gaussian pyramid
• Enhanced performance for thinning and skeletonization using bwmorph function, and for filtering RGB images using imfilter function
• Enhanced ROI behavior for imcrop, roipoly, and roifill functions
• Expanded modular interactive GUI-building tools with two new functions (imputfile and imsave) that enable saving images
• Support for reading NITF and Radiance High Dynamic Range (HDR) images

See the Release Notes for details.

Version 5.4

Released: 01 Mar 2007
 
Version 5.4, part of Release 2007a, includes the following enhancements:

• imresize function that runs faster, uses less memory, supports new interpolation methods, and supports new options for specifying output size
• applycform function that uses tetrahedral interpolation for profiles containing multidimensional lookup tables, and returns more accurate results
• The Control Point Selection Tool enhanced visual appearance, improved usability, and support for use in scripts
• impoint, imline, and imrect functions to support interactive placement, and now imrect also supports interactive resizing
• New montage parameters that control the arrangement and appearance of the images displayed

See the Release Notes for details.

Version 5.3

Released: 01 Sep 2006
 
Version 5.3, part of Release 2006b, includes the following enhancements:

• New dicomlookup function for searching DICOM data dictionary for attributes
• Performance of the dicominfo function significantly improved
• Added symmetric option to graycomatix function that produces graylevel co-occurrence matrix (GLCM) that is symmetric across its diagonal
• The iccread function supports named colors in ICC profiles
• The imdistline function now uses a different cursor shape at its endpoints to enhance usability

See the Release Notes for details.

Version 5.2

Released: 01 Mar 2006
 

Version 5.2, part of Release 2006a, includes the following enhancements:

• The iccread and iccwrite functions have been updated to support recent changes to the ICC specification.
• The iccread, makecform, and applycform functions can now read and process DeviceLink, ColorSpace, Abstract, and Grayscale profiles.
• The iccread function can now read parametric curve types.
• Three new utility functions control what happens when a figure's mouse pointer moves over and then leaves an object.
• A new utility function specifies drag constraints for the imdistline, imline, impoint, and imrect functions. (Drag constraints limit the ways that you can move line, point, and rectangle objects in a figure.)

See the Release Notes for details.

Version 5.1

Released: 01 Sep 2005
 

Version 5.1, part of Release 14 with Service Pack 3, includes the following enhancements:

• Support for two new medical image file formats: Analyze 7.5 and Interfile
• Image Tool enhancements and improvements: new Distance tool, redesigned Adjust Contrast tool, and new Window/Level mode
• New point, line, and rectangle functions to create points, lines, and rectangles that can be dragged and (in some cases) resized in a figure window
• Two new utility functions for use with profile-based color conversion functions: iccroot and iccfind

See the Release Notes for details.
