Abstract

Subband coding of images has received considerable attention and has become an effective tool for image compression. In the work by Karlsson and Vetterli (1988), a 3-D subband coding of video using 2-tap symmetrical short-kernel filters for vertical filtering was suggested for transmission over packet-switched network environments. A modified short-kernel filter pair is proposed to eliminate the coding delay and to improve the reconstructed image quality. Simulations are conducted and satisfactory results are achieved
