The RidgeRun OpenCV fork is a modified version of the project with various improvements around speed and efficiency. While some changes are general (i.e.: any platform will benefit from them), others are specific to the NVIDIA Jetson family.

The fork is hosted at: 

https://github.com/RidgeRun/opencv

These enhancements are being curated to be pushed mainstream. The progress of this effort will be kept here.
