Optical and electro-optical architectures for the compression and encryption of discrete signals and imagery: 3. Optical computation over compressed data

摘要

Abstract: Due to a reduced space requirement, the output of compressive transformations can generally be processed with fewer operations than are required to process uncompressed data. Since 1992, we have published theory that unifies the processing compressed and/or encrypted imagery, and have demonstrated significant computational speedup in the case of compressive processing, In this paper, the third of a series, we extend our previously reported work in optical processor design based on image algebra to include the design of optical processors that compute over compressed data. Parts 1 and 2 describe optical architectures that are designed to produce compressed or encrypted imagery. !43
