| 摘 要： | 通过CT系统取得平动低分辨率图像序列,采用分级块匹配像素内配准进行运动估计,应用结合小波的改进凸集投影算法重建出超分辨率图像。对CT切片图像的处理结果表明,该方法能有效提高切片图像的分辨率,为工业CT图像增强,以及其在无损检测上的应用提供一种新的手段。

| Abstract: | Super-resolution image was reconstructed by wavelet improved convex set projection algorithm, by using low-resolution image sets which obtained by CT system, and motion estimated by alignment within hierarchical block-matching pixel.The experimental result on CT slice image processing shows that the method can effectively improve the resolution of the slice images, and enhance the industrial CT image.It provides a new application in non-destructive detection. |
