| 摘 要： | 根据离焦模糊图像的特性,提出一种新的离焦模糊图像边缘检测算法,该算法通过定义一个新的边缘检测算子,利用新算子对图像各像素进行卷积,求得各像素的梯度和方向信息,根据梯度和方向信息进行阈值化处理,得到离焦模糊图像的边缘检测图像。实验结果表明,对于离焦模糊图像,利用新的边缘检测算子进行边缘检测,能够较好地检测被模糊而弱化的边缘,检测效果符合人眼视觉感受。

| Abstract: | According to the characteristics of defocused image,proposed a new method of defocused image edge detection.This edge detection algorithm by defining a new edge detection operator,using the new operator of the image of all pixels convolution,obtained the pixel the gradient and direction of information,according to the gradient and direction of information processing threshold obtained the edge detection image of defocused image.Experimental results show that for defocused image,using the new operator for edge detection,is better able to detect the vague and weakened edge and the results can reflect people＇s subjective feeling. |
