摘要: A method of performing chroma-key coding including the steps defining color regions and quantifying number pixels in regions, classifying macroblocks accordance with thus quantified, assigning chroma complexity weights for use computation quantization step-size based on classification macroblocks, computing step-size, variable length coding.
