摘要
针对常规的POCS(凸集投影 )算法会产生边缘振荡效应这一问题 ,提出了一种改进的POCS算法 ,该算法先对图像边缘像素点进行特殊处理 ,再对图像中其余的像素点进行修正 ,消除了恢复结果中的边缘振荡效应 .将改进的POCS算法与常规的POCS算法进行对比实验 。
An improved POCS (Project onto Convex Sets) was proposed to solve the edge oscillatory effect caused by general POCS. By this algorithm, the edge pixels of image were managed with special technique, while the other pixels were modified, thus the edge oscillatory of the restored image was eliminated. Contrastive experiment between the improved and general POCS algorithms was conducted which verifies the validity of the improved POCS algorithm.
