Application of short-kernel filter pairs for temporal filtering of image sequences

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.<
