摘要：

A standard compliant multiple description coding based on regions of interest is presented for protecting a region of interest (ROI) in an image sent over lossy communication networks. The multiple description coding is introduced based on multiple-path transmit framework, which can offer a variety of tradeoff between transmission robustness and code efficiency, and the original model can be achieved by generating several subsets from the original image data. The proposed method exploit polyphase downsampling to split the original image date multiple descriptions. For the sake of protection, a higher bit rate is adopted in coding the ROI. Simulation shows the proposed method can offers intrinsic resiliency in case of loss in addition to effective ROI protection.
