Description

Quantitative and qualitative analysis of NDE radiograph film is often accomplished using image processing tools. A prerequisite for such analysis is transformation of the data contained in the physical x-ray film into discrete numerical data suitable for image processing. Such transformation, called image acquisition or digitization, will introduce noise and spurious information (artifacts) into the original data. While certain qualitative data enhancement processes are tolerant of these data anomalies, significant errors may preclude quantitative analysis such as flaw sizing or flaw detection.
