Image coding with the MAP criterion

Eriksson, Tomas LU ; Novak, Mirek LU and Anderson, John B LU (2002) Proceedings DCC 2002 Data Compression Conference In Proceedings, IEEE 2002 Data Compression Conference p.453-453
Abstract
BCJR based source coding of image residuals is investigated. From a trellis representation of the residual, a joint source-channel coding system is formed. Then the BCJR algorithm is applied to find the MAP encoding. MAP and minimized squared error encoding are compared. The novelty of this work is the use of the BCJR algorithm and the MAP criterion in the source coding procedure. The source encoding system described preserves more features than an MSE based encoder. Also, blocking artifacts are reduced.
