Bounding Lossy Compression using Lossless Codes at Reduced Precision (1301.0026v1)
Published 31 Dec 2012 in cs.MM, cs.IT, and math.IT
Abstract: An alternative approach to two-part 'critical compression' is presented. Whereas previous results were based on summing a lossless code at reduced precision with a lossy-compressed error or noise term, the present approach uses a similar lossless code at reduced precision to establish absolute bounds which constrain an arbitrary lossy data compression algorithm applied to the original data.
