HP systems for evaluating video quality of compressed video........ newsalert.com <<The first demonstration includes the Objective Picture Quality Analyzer (OPQA), which was developed by the research laboratory of KDD Japan and represents a completely source-independent, real-time solution. Perceived picture-quality degradation can be assessed using any video source selected by the customer, including a live link, permitting customers to analyze their own actual video content. KDD's OPQA methodology is based on key characteristics of human visual perception. OPQA performs a precise comparison between the original and reconstructed video, and then calculates a reference value based on a set of weighted factors that incorporate the various elements and processes used by the human eye to "build" and evaluate a video picture. OPQA can be used to evaluate MPEG video codecs, monitor video transmissions, and compare and benchmark video quality across vendors. The second demonstration features compressed domain quality assessment, a technology developed by HP Labs that allows assessment of picture-quality degradation by analyzing the MPEG-2 video data stream in the compressed domain. Compressed domain quality assessment does not require access to the original, uncompressed video, permitting objective quality measurement at any point in the transmission chain. Compressed domain quality assessment analyzes any MPEG-2 encoded video data stream, and computes and graphs distortion introduced by the MPEG compression process. >>
