ABSTRACT:
Method and apparatus for providing an estimate of the size of a compressed signal without actually compressing the signal. A compression estimation mechanism models the behavior of entropy encoders on the transform coefficients generated by the application of a discrete transform method on an input uncompressed signal. The compression estimation mechanism may be used to predict a lower bound and upper bound on the size of the compressed signal from the entropy encoders, or alternatively an estimated size of the compressed signal. Since embodiments use a model of the behavior of entropy encoders to predict the bounds of the compressed signal or the size of the compressed signal without performing the actual entropy encoding, the bounds or size estimate may be predicted in less time than it takes to perform full compression of the signal.
