An Introduction to Real-Time Video Processing

An introduction to the power of the GPU using CUDA or OpenCL for real-time video processing.

We will process a short video clip from a video file using OpenCV (or fall back to using already-prepared uncompressed data), one frame at a time, and use a simple filter to apply some special effects to it. The video can be then be processed and viewed. The more efficient the code, the faster the frame-rate will be.

To make it more interesting, we will change the colour of Luke's light-sabre in a short clip from ROTJ to any colour you choose.

This simple example can be used as a basis for any video processing you might want to do on your own.
