Goal: A complete set of OpenCV 3.1 bindings for Torch, with almost all toolboxes (including CUDA, excluding OpenCL). It's going to be like OpenCV's Python bindings, but using Torch Tensors instead of numpy.

Here's an example of code.

Generally, you should refer to OpenCV documentation. Most functions' signatures match their C++ originals, but some of them, for example, exclude OutputArrays, so please check functions' definitions in cv/<module-name>/init.lua. In Python, help(cv2.someFunction) is provided; we're working on the same feature for TREPL: ? cv.someFunction.

Tutorials for users:

• Installation
• OpenCV basics: reading, converting, transforming images
• <...> Coming soon...contribution is welcome!

1. What we mostly need at the time being are unit tests and smoke tests for the work that is already done. Watch the issues as well.
2. See the issues list for the work to be tested.
3. Let's work via pull requests.
4. Please check the tutorials first, and consult with the existing code. For example, imgproc module has examples for almost every pattern that you might encounter.
