MH (Modified Huffman)

process, decompressing the data in order to reconstruct a facsimile of the original image. Modified Huffman is a lossless compression technique, as no data is lost during the compression and decompression processes.

Group III fax machines operating at 9.6 kbps transmit documents at business letter quality at a rate of approximately 30 seconds per page, using the MH compression algorithm. MH is supported by all Group III devices as the lowest common denominator, yielding a compression ratio of about 20:1 in black and white. See also compression, encode, facsimile, Group III, Huffman coding, and run-length encoding.
