| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a resolution enhancement method of motion blur video sequences. From a blurred low resolution video sequence, the proposed method simultaneously estimates a high resolution frame and a point spread function (PSF) by maximizing their posterior probability, i.e., Maximum a Posterior estimation scheme. In the PSF estimation, a region including many edge pixels are automatically selected within the target frame based on the intensity gradient. By utilizing the region suitable for the PSF estimation, its accuracy is improved, and accurate motion blur removal and the resolution enhancement are also realized. | |
