Image compression with transform coefficient analysis |
摘要 |
A method of image/video compression with intra-coding blocks analyzed for sum of absolute magnitudes of AC coefficients of DCT of block to determine whether to approximate the block with 0 AC coefficients, and with inter-coding blocks analyzed for sum of absolute differences of block and predicted block to determine whether to approximate the block with a 0 block.
