MatImage is a Matlab library for analysis and processing of digital images. It contains functions for processing, analysis, and exploration of 2D, 3D, grayscale or color images. It is built as a complement to the Image Processing Toolbox (IPT), and provides additional features as well as integration of IPT functions into more elaborate functions.

To install the library, with all sub-directories, run the script installMatImage.m.

The library is organised into several modules.

• imFilters - Image filtering (smooth, enhance, gradient...)
• imMeasures - Measurement of various parameters in digital images
• imShapes - Generation of images representing geometric shapes
• imStacks - Functions for manipulation and display of 3D images
• imMinkowski - Geometric measures (Surface area, Perimeter...) in 2D or 3D
• imGeodesics - Propagation of geodesic distances in images
• util - General purpose functions A comprehensive help is provided in each module directory.

Some functions need the MatGeom library, also available on GitHub (http://github.com/dlegland/matGeom)
