Title:
SYSTEM AND METHOD AND COMPUTER PROGRAM PRODUCT FOR PARAMETER ESTIMATION FOR LOSSLESS VIDEO COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2011/162964
Kind Code:
A3
Abstract:
Methods and systems to improve the efficiency of video processing. Compression/ decompression efficiency for a current frame may be enhanced by using an appropriate coding parameter. To choose an appropriate coding parameter, a histogram of the previous frame's symbols may be created. The histogram may be used to predict the number of bits the current frame will contain after lossless compression, given a specific coding parameter. Iterating through all of the possible coding parameters on the previous frame histogram may yield a well-suited coding parameter with which the current frame can be compressed. This results in high compression efficiency by using the previous frame as the predictor.
