Lossy and lossless image compression using reversible integer wavelet transforms

Abstract

There has been recent interest in using reversible integer wavelet transforms for image compression. These transforms allow both lossless and lossy decoding-by resolution and/or accuracy-using a single bitstream. We investigate the lossless and lossy performance of these transforms in the JPEG-2000 Verification Model O. The lossless compression performance of the presented method is comparable to JPEG-LS. The lossy performance is quite competitive with other efficient lossy compression methods.
