A blind super-resolution algorithm and the framework based on multiframe are proposed to solve low-resolution problem.Firstly,the observed low-resolution video frames are preprocessed.Then,the relative motions of them are estimated.Finally,the projection iteration is adopted step by step to reconstruct a high-resolution image under the condition but monitoring system model and related parameters are unknown.Some real video monitoring images are used in the experiments and the proposed algorithm is evaluated through subjective feelings and a variety of objective indicators.Results show that the spatial resolutions of reconstructed images are improved and the edge information is recovered.The algorithm is proved to be robust and effective.
