Packetized image communication over lossy channels presents a reconstruction problem at the decoder. To date, reconstruction algorithms have been developed for fixed coding techniques. This paper examines the dual problem — a block-based coding technique, namely a family of lapped orthogonal transforms (LOTs), is designed to maximize the reconstruction performance of a fixed reconstruction algorithm. Mean-reconstruction, in which missing coefficient blocks are replaced with averages of their… CONTINUE READING
