Code for Computer Vision Algorithms

The standard source for code to implement basic computer vision algorithms is the OpenCV Library from Intel. Many research groups build on top of this OpenCV code base. The avaliability of code for specific techniques or applications is harder to predict, but some implementations are made available by the authors and others are available from commercial vendors. The following pointers are organized somewhat by what the code does, and often by what the code is written in. If you follow the link for the reference you may find many related papers in the Computer Vision Bibliography. A number of lists of code for sub-areas (e.g. OCR) have been created by researchers in the past, but often these are no longer maintained. These lists are included in the above listing along with many of the individual entries in those lists. Current research and applications are highlighted in various general and topical Computer Vision and Image Processing conferences, especially applications workshops.
