As a practical developer I would like to make a good algorithm for my specific task, built from blocks, like a 'boundary extraction', or 'gamma correction' and so on, but I don't want to implement the wheel, making all that stuff, so I wander - if there's any powerful CV library, like C++'s OpenCV?
Saying "the best", I mean library having following properties:
- Lot of different algorithms implemented
- Extensibility - I can create new stuff in terms of the library
- High performance
- Thread safety
