ERROR RECOVERY IN FACSIMILE WITHOUT RETRANSMISSION

摘要

This paper develops and studies techniques for recovery from transmission errors that occur in facsimile images compressed with the Group 3, Extended 2 Dimensional MMR coding. When an error occurs in an MMR coded bitstream, the bitstream cannot be decoded after the error point, and the decoded image will have nothing after the error position. To prevent losing all information after an error, we develop techniques that utilize syntactical structure information of the coded bitstream to recover nearly all the data.
