Abstract:In this paper, a new image sequences blind super-resolution algorithm was proposed to reduce the influence on super-resolution construction caused by point spread function estimation error. First, we use slanted-edge method to achieve an accurate estimate of the image system’s point spread function, then combined the point spread function with the iterative back projection super-resolution construction algorithm to finish the super-resolution construction. Experimental results indicate that the proposed method needs shorter operation time and doesn’t limited by the blur degree of the low resolution image. The construction result is of higher peak signal to noise ratio (PSNR) and structure similarity (SSIM) and lager extent of the image’s true resolution.
