Abstract
To transmit facsimile images through a very low bit-rate channel such as the half-rate mobile channel, a very efficient coding scheme for data compression is required. Lossy coding is expected to perform more data reduction than that achieved by the conventional lossless coding schemes. This paper discusses approximate representation of scanned character patterns for data reduction. First, the quality of character patterns is considered in terms of the size of patterns. According to this consideration, the attributes of scanned character patterns and the quality associated with them are assumed. For preserving quality under approximation, a character pattern is described by a set of strokes in tree data structure.
