METHOD AND APPARATUS FOR ENCODING IMAGE BY EXPONENTIAL GOLOMB BINARIZATION USING OPTIMAL THRESHOLD, AND METHOD AND APPARATUS FOR DECODING IMAGE BY EXPONENTIAL GOLOMB BINARIZATION USING OPTIMAL THRESHOLD
METHOD AND APPARATUS FOR ENCODING IMAGE BY EXPONENTIAL GOLOMB BINARIZATION USING OPTIMAL THRESHOLD, AND METHOD AND APPARATUS FOR DECODING IMAGE BY EXPONENTIAL GOLOMB BINARIZATION USING OPTIMAL THRESHOLD
A method and apparatus for coding an image by using exponential Golomb binarization are provided. The method comprises: performing entropy coding on an input image by performing exponential Golomb binarization using a plurality of predetermined thresholds; measuring a bit rate of a bit stream which is generated by performing the entropy coding using each threshold; and determining an optimal threshold by comparing bit rates with regard to the thresholds.
