摘要
本文提出一种在运动模糊图象中检测边缘的方法。因为仅仅考虑图象的边缘信息,不涉及图象的大面积灰度,所以检测过程不需要先验知识及待调整参数。经过一次微分及一次边缘检测处理,模糊图象化为移动前边缘图象与移动后边缘图象的迭加,再经过移位和门限处理,即可检测出未经模糊的边缘图象。计算机模拟实验示出,这种方法是可行的。
Au approach to detect edges in motion—blurred image is presented. After a differential operation and edge detecting processing, the blurred image is turned into two superposed images, which is formed by a pre — motion image and post—motion image. Processed by shifting and thresholding, the edgescan be extracted from the original blurred image.
