摘　　要：数字图像的边缘检测在图像分割、模式识别、机器视觉等中有很重要的作用。灰度图像的边缘检测通常都基于灰度的梯度变化,而图像的直方图就描述了一幅图像的灰度级内容,通过实验找到了数字图像的边缘检测与图像的直方图之间的内在联系,得出具有双峰直方图的图像,其边缘检测效果是比较好的。The edge detection of numeric picture has a very important function in the image segmentation, pattern recognition, and machine vision and so on. The edge detection of the gray image usually is done according to the change of gradient of gray, and the image histogram describes an image gray content. In this paper, it is found out that there are certain internal connections between the edge detection of a numeric image and the image histogram of a numeric image, and draws a conclusion: the image has the doub...
