MatImage 1.2.5

MatImage is an image processing library for Matlab, build as a complement of the Image Processing Toolbox. It provides a large number of functions for image processing (filtering, enhancement, editing, conversion...), image quantification (color histograms, joint histograms, region analysis, gray level granulometry...), import of specialized 3D image data, as well as the "Slicer" graphical user interface for quick exploration of 3D images. A large number of functions can be applied on images independently of their type (binary, grayscale, color...) or dimensionality (2D or 3D).

The 1.2.5 version mostly enhances the user manual and the documentation.
