LTI-Lib
image processing library, LGPL
LTI-Lib is an object oriented library with algorithms and data structures frequently used in image processing and computer vision. It is being used in many research projects in computer vision dealing with robotics, object recognition and sign language and gesture recognition. The main goal of the LTI-Lib is to provide an object oriented library in C++, which simplifies the code sharing and maintenance, but still provides fast algorithms that can be used in real applications.
