This paper develops and studies interactive techniques for recovery from transmission errors that occur in facsimile images compressed with Group 3, Extended 2 Dimensional MMR coding scheme. When an error occurs in an MMR coded bitstream, the bitstream cannot be decoded after the error point. To prevent losing all information after an error, we develop standalone and interactive error recovery systems that utilize syntactical structure information of the coded bitstream to recover nearly all the data. The standalone recovery works well on text documents or regular graphics, but cannot handle more complex document structures. Interactive recovery, sing feedback from a user, can recover from errors in a wide range of document types.
