A transform coding scheme for imagery based on detection

The use of data compression schemes is in many cases of great importance when images are to be transmitted. Compression methods that exploit spatial and temporal statistical dependencies in an image frame or an image sequence have been suggested. This work comprises a new intraframe compression technique which combines a classification algorithm and a transform coding to obtain significantly higher compression ratios than obtained by transform coding alone. Some results obtained by the scheme are presented and their evaluation is discussed.
