This paper considers an alternative image representation scheme, based on Gaussian derivatives, to the standard discrete cosine transformation (DCT), within a JPEG framework. Depending on the computer arithmetic hardware used, the approach developed here might yield a compression/decompression technique twice as fast as the DCT and of (essentially) equal quality.application/postscriptenIn CopyrightTechnical reportTR-95-22http://eprints.cs.vt.edu/archive/00000437/01/TR-95-22.ps
