数字化射线检测中缺陷影像的频域处理
The Image Processing of Digital Radiography in Frequency Dominant
摘 要
研究频域处理在数字化射线检测缺陷影像增强处理过程中的应用。采用Matlab 7实现高通滤波处理流程，对处理结果进行分析，证实频域处理可有效改善数字化射线检测的灵敏度、提高图像分辨率。将其用于各类典型缺陷的数字化射线检测影像处理，可提高缺陷的检出率。

Abstract
The application of frequency domain treatment in digital radiographic testing(DR) image enhance processing of the flaw image had been explored. The processing method of high pass filtering was implemented by Matlab 7. It was proved that the frequency domain treatment could effectively improve the figure sensitivity of the DR. The frequency domain treatment was used practically in the image processing of DR with kinds of classical defects. it was validated that the detectable rate could be improved greatly.
