Image Processing with OpenGL and Shaders (LinuxJournal)

The Linux Journal has an article on computing with the GPU. "This article discusses using OpenGL shaders to perform image processing. The images are obtained from a device using the Video4Linux 2 (V4L2) interface. Using horsepower from the graphics card to do some of the image processing reduces the load on the CPU and may result in better throughput. The article describes the Glutcam program, which I developed, and the pieces behind it."
