Abstract: “Multi-resolution analysis has been a very popular with compression specially in video streaming because it eliminates the blocking effects of the DCT which become more prominent in videos. Wavelets are based on the multi-resolution but it is well acknowledged that wavelets are far more expensive in terms of hardware and software as compared to DCT. DCT, however, has been used to compress image but not for multi resolution image analysis.”

Keywords: Discrete Cosine Transform, Image Compression, Multi-Resolution Analysis and DCT.
