Adaptive multiresolution decomposition: Application to lossless image compression

In this paper we introduce the use of adaptive filter banks in lossless compression of images with progressive coding in resolution. During the decomposition the filter adapts itself automatically to various regions of the image, preserving the perfect reconstruction property. Effects of parameters used in the decomposition have been studied. Simulation results are given and compared with well-known codecs. The proposed scheme gives, on average, smaller lossless compression bit rate. However, This improvement in performance is achieved at the expense of an increase in computational complexity.
