| 摘 要： | 在现代无损检测技术中，图象处理技术用来定量或定性分析和发现设备的故障，并得到了普遍应用。本文根据射线图角的特点，介绍一种在实时成象检测中，对所得的图角进行空间域自适应对经度增强的算法，试验表明，该算法实时性好，能使原图象中较模糊、对比度差的细节得到明显的增强。同时根据以变换的多分辨率特性，在小波域也进行了尝试。

| Abstract: | Quantitative or qualitative analysis and detection of equipment failure,adopting image processing techniques,have been widely used in modern nondestructive tests.This paper,based on the characteristic of ray image,introduces a spatial domain self adaptive contrast enhancement alogrithm for the image available in real time imaging test.Experiment has shown that this alogrithm has a good real time effect,remarkably reducing the blur and greatly enhancing the contrast of the original image,besides,this alogrithm has been attempted in wavelet domain auording to the characteristic of multi resolution ratio of wavelet transforms. |
