C++ library of image understanding-related algorithms

 Iulib provides basic image processing, mathematical morphology, and machine
 learning algorithms.
 .
 Iulib implements easy-to-use image and video I/O functions, as well as a
 large number of common image processing functions.
 .
 Design goals are high portability, easy-to-understand algorithms, no
 reliance on STL, and using a minimal set of data structures. Almost all
 interfaces are written in terms of just numbers and the simple narray array
 class.
