A multiple description image/video coding method by compressed sensing theory

Multiple description coding (MDC) has emerged as a promising approach to enhance the error resilient property for video transmission. This paper proposes a novel MDC method by incorporating a newly appeared signal recovery theory, compressed sensing (CS) theory, into image/video coding framework. The compressed sensing theory states that under certain conditions, a signal can be precisely reconstructed from only a small set of measurements. Taking this advantage, the proposed MDC method generates multiple descriptions in the frequency domain, enabling each description to recover original signals properly and the more descriptions the better quality. Experiments have demonstrated the feasibility and advantage of the proposed MDC scheme.
