ABSTRACT:
A method and apparatus for selecting a quantizer scale for each object within a frame to optimize the coding rate is disclosed. A quantizer scale is selected for each region or “object” within each frame such that the target bit rate for the frame is achieved while maintaining a uniform visual quality over the entire frame.
