| 摘 要： | 为解决利用经典的POCS(Projection onto Convex Set)算法进行图像重建时所产生的边缘模糊问题, 提出了具有边缘保持特性的POCS 超分辨率重建算法。根据待插值点的邻域特征判断该点所在区域是边缘区域还是非边缘区域, 利用改进的双线性插值算法构建参考帧, 减小了传统算法重建后图像边缘的模糊现象。结果表明, 该方法能得到具有较好边缘质量的高分辨率重建图像。 |

| Abstract: | In order to solve the problem of edge blur in image reconstruction using the traditional POCS (Projection onto Convex Set) algorithm, A super-resolution image reconstruction of POCS with edge preserving is proposed. According to the neighborhood of interpolation pixel, the area of the pixel is the edge region or the non edge region. Reference frame is constructed by the improved bilinear interpolation algorithm, reducing the blur of the image edge after the reconstruction of the traditional algorithm. Experiment results demonstrate it can obtain high resolution reconstruction images and image edge isbetter. |
