The first place to look for basic code to implement basic computer vision algorithms is the OpenCV Library from Intel. Many research groups build on top of the 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, with other links by what language the code is written in. If you follow the link for the code reference you may find links to the related papers in the Computer Vision Bibliography. Additionally, following the link to the Author often leads to a site with more code. A number of lists of code for sub-areas (e.g. OCR) have been created by researchers in the past, but too often these are no longer maintained. These lists are included in the my 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. As always, the links may not work for all time -- I have no control over the actions of others who move or delete files, but often broken links can provide a starting place to find the source.

Computer Vision resources include:

- Computer Vision Conference Listing
- Code for Computer Vision Algorithms
- Available Datasets
- Computer Vision Topical Surveys
- Vendors. These may also have related research groups.
- Research Groups
- Researchers within Research Groups and Researchers with unlisted groups
- Browse Papers by Author Name
- Professional Societies
