Hybrid error concealment in image communication using data hiding and spatial redundancy

Designed to diminish the artifacts caused by application of the state-of-the-art error concealment methods, a hybrid error concealment scheme is introduced. The proposed scheme stands out by using the inherent spatial redundancy of natural images along with a data hiding technique to obtain the information required for reconstruction of the lost parts of the image at the receiver. Furthermore, to maintain the quality of the received image in high packet loss conditions, an alternative scheme is proposed which will be activated in response to a receiver’s feedback reporting a high packet loss ratio. Our simulation results show that the proposed scheme outperforms the existing methods in terms of the quality of the received image and computational cost.
