HIERARCHICAL VIDEO ANALYSIS-BASED REAL-TIME PERCEPTUAL VIDEO CODING

A system for encoding a video stream into a processed video signal that includes at least one image. The system includes a downscaling module, a partitioning module, a rate control module, and an encoder section. The downscaling module receives the video stream and produces a downscaled video stream. A partitioning module, including a region detection module, receives the downscaled video stream and detects a pattern of interest in the at least one image. The partitioning module is operable to partition the at least one image based on the detected pattern of interest. The rate control module that receives an output from the partitioning module and produces an encoder control signal dependent on the output from the partitioning module. The encoder section, coupled to the rate control module, receives the video stream and generates the processed video signal.
