Non-stationary two-dimensional subband transformer filters
Vladimir Čeperković, Milan D. Prokin · 2012
State-of-the-art two-dimensional subband transformation based compression methods typically require large memory size and memory bus bandwidth. This paper discloses a novel method for reducing both shortcomings, and even providing compression or decompression from the cache memory. This solution can be implemented either in software or hardware or their combination, as a front stage in either lossless or lossy image encoder or backstage in either lossless or lossy image decoder.
