cl-jpeg
JPEG encoder implementation using OpenCL
This is a research project to test GPU (OpenCL) usability for image compression. Jpeg format is chosen because it is relatively simple and I am familiar with it.
2013-01-22: For now only pixel conversion and DCT transform is done with OpenCL, entropy coding is done with CPU in one thread. Unfortunately this implementation is no match for even one threaded SSE2 jpeg encoder, too much data goes through PCIe.
