梯度和散度在弹丸图像边缘提取中的应用

本文将场论中等位线,梯度和散度的概念引入到图像分析中,基于梯度和散度的积分定义,结合图像梯度和散度的与坐标选取无关的简易近似公式,分析灰度图像梯度和散度的物理意义。本文将上述理论总结为一种图像处理方法,应用于弹丸的边缘的提取中,本文方法处理结果比动态边缘提取算子canny所提取的结果更理想。

Appliance of Gradient and Divergence to Compute the Edge of Bullet image

Isolinie,gradient and divergence of theory of gravitational field are introduced into image analysis.Based on the integral def- inition of gradient and divergence, and that image gradient and divergence is independent of the coordinate, physical meaning of gray image gradient and divergence is analyzed. In this paper, a new image processing method is summarized from this theory, and ap- plied to compute the edge of bullet. The bullet edge computed by the method in the paper is idealler than that computed by canny operator.
