Abstract

The design of an algorithmically specialized processing module capable of implementing arbitrary geometric transforms on discrete image data is described. Applications include geometric image correction, image mapping, and real-time computer graphics and display systems. Following a discussion of the inherent design complexities involved, several potential solutions and their relative merits and shortcomings are discussed. Of particular importance is the use of a binary or bit plane approach where k-bit pixel data is geometrically transformed one bit plane at a time. This is achieved via a massively parallel pixel destination address calculation and use of either an associative memory (AM) or a bit-plane AND-ing operation. The output bit-plane is formed using row and/or column decoders with OR-ed outputs. Future research directions are outlined.
