This paper proposes a new spatio-temporal resolution enhancement method of video sequences based on super-resolution reconstruction. The proposed method uses obtained homography matrix's parameters based on feature points correspondence for calculating the pixel correspondence between successive frames. In this procedure, the proposed method clusters the feature points correspondence and calculates the homography matrix's parameters from the feature points correspondence in the largest cluster. By using the obtained parameters, camera parameters are calculated accurately. Furthermore, from the camera parameters, we estimates the pixel correspondence between the successive frames and the interpolated one. With the obtained motion vector, we apply the super-resolution reconstruction. Consequently, we can obtain an accurate high-resolution and high frame rate video sequence. Simulation results are shown to confirm the high performance of the proposed method. |
