Project Summary: Traditionally, the radiographic images created by exposure of film are considered by trained experts searching for a possible defect in the provided projection of the industrial part. Concerning a total simulation of the inspection procedure, the expert's more or less subjective decision criterion on the presence of a defect has also to be modelled to provide meaningful simulation results. The aim of this work is to further develop existing visibility criteria and, if necessary, to search for a new criterion to improve the simulation of radiographic inspection procedures in industrial applications, especially in the field of the nuclear power industry.

项目摘要：传统上，通过胶片曝光产生的射线照相图像是由训练有素的专家在提供的工业部分投影中寻找可能的缺陷。对于检查过程的全面模拟，专家或多或少的主观判断标准的缺陷的存在也必须建模，以提供有意义的模拟结果。这项工作的目的是进一步发展现有的可见度标准，并在必要时寻求一种新的标准，以改进工业应用中放射照相检查程序的模拟，特别是在核动力工业领域。
