| 摘 要： | 传统的凸集投影（POCS）超分辨重构算法易使图像产生边缘振荡效应问题，在研究了边缘振荡效应的成因后，提出一种基于线过程模型的POCS算法来对低分辨图像序列进行超分辨图像重构．该算法采用线过程模型检测出超分辨初始估计图像的4个方向的边缘，在传统POCS的投影过程中增加了对图像的平滑处理，实现了低分辨图像序列超分辨重建的对比实验，实验结果表明图像边缘振荡效应能得到明显改善．

| Abstract: | In view of ringing artifacts reduction of traditional POCS(projections onto convex sets) super-resolution image reconstruction algorithm,a novel POCS algorithm based on line process model is presented in this paper after analyzing the cause of these artifacts.Smooth processing is added in the projection of the traditional POCS,according to the four orientations edges of initial estimation of super-resolution image detected by the line process model.A super-resolution image is reconstructed by several low-re... |
