Abstract
A new synthetic high coding is presented for high data compression. In this scheme, only the lowpass image is transmitted, which is composed of the low-frequency components of an image, through subsampling and adaptive transform coding (ATC). Then it is expanded by interpolation at the receiver. The highpass image is simply synthesised without any overhead information by edge-sharpening the expanded lowpass image. The result of the proposed scheme shows acceptable image quality even at a high compression ratio of about 30:1
