查询词典 detection

In the Sixth Chapter, the Wavelet analysis method is introduced in discussing some acoustic imaging problems related to the physical background of the ultrasonic detection. In the light of the solution of some theoretical problem in the 2D Wavelet transmission of two components form, the enhancement and identification of the spotty and fibriform faults of the acoutic image, along with two acoustic image deblurring methods based respectively on the acoustic physical feature analysis and the acoustic image's spatial feature analysis of the object, are realized. Therefore the image degeneration problem resulting from the acoustic beam diffusion or the acoustic focus diffusion in the ultrasonic detection are effectively improved. The software for this purpose has also been developed.

第六章首次应用小波分析的方法，研究了与超声检测的物理背景有关的一些声象处理问题，在解决了二分量形式的二维小波变换中的一些理论问题的基础上，建立起了对声象中点状和线状缺陷目标的增强与分离方法，以及分别基于目标的声学物理特征分析和基于目标声象空间特征分析的二种声象弥散消除方法，实验分析结果表明，这种方法较好地解决了超声检测中由于声束截面或声焦点扩散所造成的成象退化问题。
