On lossless image compression using the Burrows-Wheeler Transform

The Burrows-Wheeler Transform (BWT) is known to be very effective in compressing text data. However, there is still a debate on its performance on images. Motivated by a theoretical analysis of the performance of BWT and MTF, we perform a detailed empirical study on the role of MTF in compressing images with the BWT. We propose two schemes for BWT-based… CONTINUE READING
