    摘要: A method of processing a video sequence is provided. The video sequence includes a plurality of video frames, wherein each of the plurality of video frames includes a plurality of macroblocks. Further, each of the plurality of macroblocks includes a plurality of pixels. The method includes determining energy values for pixels in a first macroblock and a second macroblock, determining a respective attenuation factor for each of the plurality of pixels in the first macroblock and determining a modified intensity value for each of the plurality of pixels in the first macroblock based on the respective attenuation factor for each of the plurality of pixels in the first macroblock, a respective intensity value of each of the plurality of pixels in the first macroblock and a mean intensity value of the first macroblock.
