Latest Patents

Zhou Wang holds a patent for a "Method and system for objective quality assessment of image and video streams." This method predicts the visual quality of a DCT (discrete cosine transform) based compressed image or video stream without referring to its source. The technique involves estimating quantization errors using MPEG quantization scales and statistics of the inverse quantized DCT coefficients. Additionally, it includes a blind estimation of the 8×8 and 16×16 blocking effect, along with an adaptive combination of these estimations using MPEG motion vector information. This method is applicable in various domains, including network video servers, switches, multiplexers for automatic quality monitoring, and control of video services.
