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 imGeodesics - Propagation of geodesic distances in images imGranulometry - Compute granulometry curves on grayscale images imShapes - Generation of images representing geometric shapes

Improvements

Version 1.2.4 fixes several bugs and introduces some new features.

• added imCropOrientedBox function to extract a rotated portion within an image
• added imTangentCrop and imTangentCrop3d.m to automatically evaluate orientation of rotated crop
• added gradientKernels and gradientKernels3d to factorize computation of gradients within 2D/3D images
• imFeretDimater: added support for 3D diameter
• several refactoring in "imGranulometry" module.
• updated the user manual
