A method based on non-local was proposed for multi-frame image of the super-resolution algorithm, which meant no need for image correction. To overcome the influence of the traditional image restoration algorithm based on local area of the impact point, we can use the model of non-local denoising maintain superior edge and denoising to reconstruct high-resolution images. This experiment proves that the algorithm in the low signal to noise ratio circumstances can achieve better results. It is an effective solution to the image with low signal to noise ratio under the conditions of difficult recovery.
