POCS-Based Iterative Reconstruction Algorithm of Missing Textures

In this paper, a new framework for texture reconstruction of missing areas, which exist all over the target image, is presented. The framework is based on a projection onto convex sets (POCS) algorithm including a novel constraint. In the proposed method, a nonlinear eigenspace of each cluster obtained by texture classification is applied to the constraint. Furthermore, by monitoring the errors converged by the POCS algorithm, selection of the optimal cluster for the target texture including missing intensities is realized in order to reconstruct it adaptively. Then, iterating the POCS-based procedures, our method renews the nonlinear eigenspaces and the reconstruction image, and outputs the reliable result. This approach provides a solution to the problem in traditional methods of not being able to perform adaptive reconstruction of the target textures due to the missing intensities. Experimental results show subjective and quantitative improvement of the proposed reconstruction technique over previously reported reconstruction techniques.
