Pandore is a standardized library of image
processing functions. The current version contains
functions for 1D, 2D, and 3D images, which may be
greyscale, color, or multispectral.
The CImg library provides a set of C++ classes
that can be used to load, save, process, and
display images. It is portable (Unix/X11, Windows,
MacOS X), efficient, and simple to use.
