Version 6.0
Released: 01 Sep 2007Version 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
demosaicfunction to convert Bayer pattern encoded images to truecolor RGB images - New
impyramidfunction to create a multiresolution Gaussian pyramid - Enhanced performance for thinning and skeletonization using
bwmorphfunction, and for filtering RGB images usingimfilterfunction - Enhanced ROI behavior for imcrop, roipoly, and roifill functions
- Expanded modular interactive GUI-building tools with two new functions (
imputfileandimsave) 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 2007Version 5.4, part of Release 2007a, includes the following enhancements:
imresizefunction that runs faster, uses less memory, supports new interpolation methods, and supports new options for specifying output sizeapplycformfunction 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, andimrectfunctions to support interactive placement, and now imrect also supports interactive resizing- New
montageparameters that control the arrangement and appearance of the images displayed
See the Release Notes for details.
Version 5.3
Released: 01 Sep 2006Version 5.3, part of Release 2006b, includes the following enhancements:
- New
dicomlookupfunction for searching DICOM data dictionary for attributes - Performance of the
dicominfofunction significantly improved - Added symmetric option to
graycomatixfunction that produces graylevel co-occurrence matrix (GLCM) that is symmetric across its diagonal - The
iccreadfunction supports named colors in ICC profiles - The
imdistlinefunction now uses a different cursor shape at its endpoints to enhance usability
See the Release Notes for details.
Version 5.2
Released: 01 Mar 2006Version 5.2, part of Release 2006a, includes the following enhancements:
- The
iccreadandiccwritefunctions have been updated to support recent changes to the ICC specification. - The
iccread,makecform, andapplycformfunctions can now read and process DeviceLink, ColorSpace, Abstract, and Grayscale profiles. - The
iccreadfunction 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, andimrectfunctions. (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 2005Version 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:
iccrootandiccfind
