| Abstract: | A framework of reconstructing a superresolution video sequence from a low resolution video sequence is proposed in this paper.Under this framework,we discuss a superresolution restoration algorithm from a single frame based on regularized least mean square functional.Its iteration formula,convergence,convexity and the choice of parameters are thoroughly studied.We also present a registration algorithm based on weight matrices.The characteristics of motion compensation matrices and weight matrices are discussed in detail.Experimental results demonstrate the power of the proposed method. |
