Spatial Error Concealment Algorithm Based On Improved SUSAN Operator
In the transmission of real-time video compressed streams, error concealment method is to restore the damaged or lost data packets. This paper improves the existing spatial error concealment algorithm based on SUSAN detection operator. On the one hand, as recovering the error, the detection pixels were reduced by considering the relationship of nearby pixels. On the other hand, more associated pixels were fully considered. The experimental results show that the proposed algorithm enhances the Peak Signal to Noise Ratio in the case of reducing 4％-8％ computational complexity, and is more beneficial to real-time application.
