MatImage 1.2.4

MatImage is an image processing library for Matlab. It is build as a complement of the Image Processing Toolbox. The matImage library is divided into several modules:

imFilters - Image filtering (smooth, enhance, gradient...)
imMeasures - Measurement of various parameters in digital images
imStacks - Functions for manipulation and display of 3D images
imMinkowski - Geometric measures (Surface, Perimeter...) in 2D or 3D
