| 摘 要： | 在分析了工业焊接X光图片特点的基础上,本文应用随机过程和随机几何学、光学成像及信号处理的理论,为该类图片选用一种参数统计模型,并解决了 Wiener 滤波器设计中的一系列问题,应用统计同志滤波的数字处理法,得到了用一些常用方法难以得到的增强效果,从而为寻求工业焊接X光图片的数学模型及增强方法进行了一次有意义的探索。

| Abstract: | Based on the X-Ray image analysis of weldment, a parametric stochasticmodel is selected with the theory of random process, stochastic geometry,optical imaging and signal processing. Also a series of problems of wienerfilter design are solved. A digital processing method, called stochastic ho-momorphic filtering, is used for obtaining a satisfactory result. A valuableapproach is made for the mathematical model and the enhancement methodof X-Ray image of industry weldment. |
