摘要
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。
Isolinie,gradient and divergence of theory of gravitational field are introduced into image analysis.Based on the integral definition 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 applied to compute the edge of bullet. The bullet edge computed by the method in the paper is ideallcr than that computed by canny operator.
