Subband-coded image reconstruction for lossy packet networks

Abstract: Transmission of digital subband-coded images over lossy packet networks presents a reconstruction problem at the decoder. This paper presents two techniques for reconstruction of lost subband coefficients, one for low-frequency coefficients and one for high-frequency coefficients. The low-frequency reconstruction algorithm is based on inherent properties of the hierarchical subband decomposition. To maintain smoothness and exploit the high intraband correlation, a cubic interpolative surface is fit to known co… Show more

“…The method proposed in [10] is based on the iterative application of a generic denoising algorithm. The main problem with the methods in [8]- [10] is that they are applicable only for small lost areas, and their performance declines significantly when the size of lost area is increased. For example, the proposed methods in [9] do not show any improvement for 8 !…”
