Abstract
DCT-based methods for fixed bit rate, intraframe compression of video are based on the visual quality of the resulting decompressed imagery. In general, this involves assigning an initial bit budget per macroblock of a given video frame, resulting in degrees of compression, i.e., quantization scale factors, that vary among the macroblocks according to their complexity. The scale factors are then adjusted while maintaining the overall frame bit budget to reduce the visibility of artifacts in the decompressed frame. The adjustments may include increasing scale factors for simple macroblocks and reducing scale factors for complex blocks. As compared to traditional DCT-based compression schemes, the described methods may reduce the visibility of compression-related artifacts both in complex and in simple portions of the frame.
