Multiple Description Coding (MDC) has attracted a lot of attention to realize robust image and video delivery. MDC encodes a source image or video into multiple bitstreams called descriptions, which can be transmitted on independent communication channels. On reception, these descriptions can be combined and decoded to reconstruct the encoded source image or video. Many methods to partition the source have been proposed. One method is to split an input image in the spatial domain by sub-sampling. Another method is to partition Discrete Wavelet Transform (DWT) coefficients using Lattice in the frequency domain. However, these methods suffer from issues such as low coding efficiency, and inadequate redundancy control among the divided descriptions. We propose a new method to partition the source by using Directional Filter Banks (DFBs). We compare the DWT method and proposed method with respect to PSNR with increased packet (data) loss. The simulation results show that at almost the same quality in PSNR the visual quality is quite different, as are the details of reconstructed images. |
