Abstract

Disclosed is a coding algorithm that uses wavelet-based compression to provide both lossy and lossless compression in the same codestream. The advantage of this approach is that compression ratio, and subsequently Mixed Raster Content (MRC) image file size can be precisely controlled, and that MRC can be easily combined with the JPEG 2000 standard.
