Abstract
A method of transferring the digital representation of a bit-mapped image which includes the steps of: (1) identifying predefined patterns in the bit-mapped image data, and (2) transmitting pattern codes corresponding to those patterns to a receiving device. The identification of the patterns involves the partitioning of the bit-mapped image into a series of pattern cells and the scanning of those pattern cells to find preselected patterns. The preferred method of searching the pattern cells is based upon the use of a hashing function and hash tables. In response to the received pattern codes, the receiving device reconstructs the bit-mapped image associated with the pattern codes. After all patterns in the bit-mapped images are identified and sent to the receiving device, the non-recognized portions of the bit-mapped image are then sent. The overall bit-mapped image is recreated by combining the recognized patterns with the non-recognized portions in their original order.
