Faroudja Patents Method For Eliminating “Banding” Artifacts When Compressing IP Video

On September 13, 2016 Faroudja Enterprises Inc., founded by video pioneer and Emmy winner Yves Faroudja, was granted a new patent, its ninth overall, entitled “De-blocking and De-banding Filter with Adjustable Filter Strength for Video and Image Processing.” The patent describes technology that eliminates “blocking” or “banding” artifacts common during the delivery of internet video when compression is applied.

Faroudja called US Patent No. 9,445,131, “one of our most valuable yet.”

According the company website, The DB1 Deblocking/Debanding algorithms eliminate blocks and banding artifacts often introduced during compression, while not diminishing details and edges. The technology is based on specialized techniques that look at large regions of uniform value with small variations, commonly introduced in the early stages of compression. Through complex processing, these artifacts are eradicated, while the resolution of the image is not affected.

One highlight of the patent’s technology is that while it reduces banding artifacts, it does not diminish details and edges. Innovative techniques are used to examine large regions of uniform value with small variations, commonly introduced in the early stages of compression. Through complex processing, these artifacts are eradicated, while the resolution of the image is not affected.
