Abstract
We present a JPEC-compliant method for the efficient compression of compound documents using variable quantization, based on the DCT activity of each 8×8 block, our scheme automatically adjusts the quantization scaling factors so that test blocks are compressed at higher quality than image blocks. Results from three different quantization mappings are also reported
