Abstract

In this paper, we propose a technique for concealing missing image/video blocks based on the concept of visual clearness of an edge. A scanning procedure based on the Hough transform allows us to find the relevant edges, and the visually clearest ones are employed in an interpolation based reconstruction. Specifically, several interpolations are combined according to a set of weights which allows the reconstruction of more complex textures. These weights are derived from the visual clearness associated to an edge and are unique for every pixel within the missing macroblock. The resulting algorithm is quite efficient, simple, and competitive in comparison with other state-of-the-art techniques.
