An Edge Preserving Spatial Error Concealment Technique for the H.264 Video Coding Standard

This paper presents a combination of algorithms which, when used together, produce a highly effective spatial error concealment technique that can be used on intra slices in the H.264 video coding standard. By first detecting edges passing through neighboring macroblocks, a weighting system can be applied to a multi-directional interpolation scheme, experimental results show that this preserves edges through erroneous macroblocks which in turn gives both significantly improved mathematical and visual performance over the commonly used weighted pixel value averaging
