Abstract
A data compression-expansion (decrease-increase) method for improving the signal-to-noise ratio of compressed-expanded data while retaining the fidelity of the original data comprises the steps of using a filter that can be separated into a smoothing portion and an enhancing portion. The selected filter is separated into the two portions: a first portion for smoothing prior to decreasing the data, and a second portion for enhancing after increasing the data whereby the filter has the maximal effect of decreasing noise while having a minimal effect on the data.
