Abstract
This paper proposes an accurate restoration and resolution enhancement method of a sequence deteriorated by camera shake based on super-resolution reconstruction. The proposed method estimates the PSF (Point Spread Function) which denotes the deterioration function of a camera shake. Then, in order to calculate the correspondence between frames in the sequence accurately, we utilize restored frames as substitutes to the original ones. Furthermore, by introducing a new weighting factor, which prevents oversmoothing in the camera shake direction, to the super-resolution reconstructon, an accurate restoration and resolution enhancement can be realized. Simulation results are shown to verify the performance of the proposed method.
