Abstract :
This paper proposes an efficient way of using edge based redundant information for improving the error resilience of IDR frames. The proposed method generates spatial error concealment mode and edge direction data at the encoder which are sent to the decoder to guide the concealment process. Results show that the method offers very good performance with only a very small increase in complexity at the decoder and the introduction of negligible overhead to the coded stream.
