Abstract
Video signals are encoded by dividing a current video frame into regions and generating a local complexity measure and a local quantization level for each region, where the local quantization level is selected using the local complexity measure, a previous complexity measure corresponding to a previous video frame, and a previous quantization level corresponding to the previous video frame. The complexity measures are generated using the DCT coefficients for each region. The region is encoded using the local quantization level to generate an encoded bit stream corresponding to the current video frame.
