本文应用随机过程论、随机几何学及光学成像和信号处理的理论,在分析焊缝射线照相特点的基础上,选用Modestino-Fries 模型,将统计的概念和统计同态滤波的方法引入该类图象的增强处理中,得到了用简单的空域处理法所难以得到的较满意的结果,从而为寻求工业焊缝射线照相的数学模型及处理方法进行了一次新的探索。 Based on the theory of stochastic process, stochastic geometry, optical imaging and signal processing, this paper selects the Modestino-Fries model based on the analysis of the radiographic characteristics of the weld and introduces the concept of statistics and the method of statistical homomorphic filtering into the class diagram Image enhancement process, obtained by the simple airspace processing method is difficult to get more satisfactory results, so as to seek the industrial welding radiography mathematical model and processing method to a new exploration.
