Abstract

Abstract: In order to reconstruct a high-resolution image from single highly blurred image, a super-resolution reconstruction method combined with adaptive regularization and learning algorithm is proposed. Based on local characteristics, the dynamic adaptive control progress of reconstruction method is achieved. Train set, prediction principle and searching progress of learning algorithm is optimized to depress the relativity of example image and improve the searching efficiency. Experimental results demonstrate the availability of the method by steps, and the improvement of reconstruction result.
