【摘要】 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。更多还原

【Abstract】 In analysing the weldment radiography,the authors,applying the theory of randomprocess,stochastic geometry,optical imaging,and signal processing,took the Mod-estino-Fries’ model and introduced the concept of stochasties and a digital processingmethod,named stochastic homomorphic filtering,into the enhancement of such images.Some satisfactory results,which would be much more difficult for those simplespatial-domain processing methods,were obtained.This thesis provides a new approachto the methematical model and processing method for practical weldment radiography.更多还原
