Spatial Error Concealment Technique using Verge Points
This paper presents a spatial error concealment technique using "verge points" which are the high-curvature points on image surfaces. Associated with curvature information, the verge points provide important characteristics in reconstructing broken edges. In our method, only a single layer of verge points surrounding the missing area are extracted. The broken edges are reconstructed by pairing these verge points with respect to both the curvature information and their neighboring pixel values. Simulations show that with our pairing criterion, most of the object edges are recovered and our concealment technique yields satisfactory results especially in terms of subjective perception.
