error-resilience is an important feature of any image or video coding algorithm associated with transmission over noisy or multipath channels. in this paper, we present a robust coding algorithm based on a modified version of the zerotree coding technique, The algorithm provides significantly improved error-resilience with minimum added redundancy while still. retaining the efficiency and scalability of tile original technique.
In this paper, a novel wavelet-based multiple description coding (MDC) is proposed with dual decomposition (DD) and cross packetization (CP). Through dual decomposition, each description has two parts, the primary and...

In this paper, we propose a region-of-interest (ROI) based errorresilient algorithm for High Efficiency Video coding (HEVC) video transmission applications. We use moving region (MR) as ROI so that the proposed method can address a wide variety of different scenarios. Based on the MR information, the depth level of each coding unit (CU) is determined. This can reduce the computation complexity of encoder significantly. A feedback channel from decoder is assumed in our system. According to feedback information and MR information, coding mode for each CU is selected. In addition, current rate control algorithm of HEVC is modified so that it can handle CU-level intra refresh. Experimental results demonstrate that the proposed method can achieve better subjective and objective quality, compared to the conventional reference picture selection (RPS) algorithm which is an effective errorresilient tool for low delay application.
