Abstract: | For the uncontrolled micro-scanning where the displacement of image sequence is random, a sub-pixel processing algorithm based on boundary recursive and subsequent error optimization is proposed in this paper. Neighboring pixels are used to approximate the boundary pixels of the original image in the algorithm. Then the approximate error is optimized by the gray statistical principle. At last a sub-pixel image with high resolution is reconstructed. The results show that our algorithm is better than the general over-sample reconstruction algorithms and robust in different displacement situations. |
