Abstract: Under the framework of L1-norm based Super-Resolution Reconstruction(SRR), by introducing a method for automatically estimating regularization parameter, a SRR method based on mixture prior model is proposed according to difference image statistics combined with probability distribution model. Experimental results indicate the proposed approach which results in good robustness and effective convergence outperforms the old one.

Key words: super-resolution, difference image, mixture prior model
