Description: G’MIC stands for GREYC’s Magic Image Converter. It is focused on the design of possibly complex pipelines for converting, manipulating,
filtering and visualizing generic 1d/2d/3d multi-spectral image datasets. This includes classical color images, but also more complex
data as image sequences or 3D volumetric images. G’MIC has been designed with portability in mind and runs on different platforms
(Windows, Unix, Mac OS X).
