In order to improve the image quality of enlarged image, the super resolution using total variation(TV) regularization has been proposed. However, the previous method without reference images has a problem that the edge distortion such as blur is occurred in the enlarged image because higher frequency information isn’t able to be estimated accurately. This paper presents new super resolution based on TV regularization that calculates two kinds of higher frequency components with edge and texture, and composes the higher frequency image by combining both components appropriately. It is seen in the experimental results that the enlarged image by the proposed method decreases the blur around edge compared with the previous method. |
