Study of Infrared/Ray Image Enhancement Method based on MATLAB
基于MATLAB的红外/射线图像增强方法研究

Usually,there are some noises caused by the factors such as stochastic disturbance etc.in the images produced by a nondistructive test system(NDT).To make a further analysis of these images,the image enhancement as an important preprocessing work is necessary.The image enhancement methods can be divided into two classes:frequency domain processing and spacial domain processing.In this paper,the image processing technologies such as gray transform and wavelet transform are introduced into the NDT image processing and the MATLAB image processing tool is used to enhance the images in two aspects of frequency domain and spacial domain.These two methods are implemented by programming in the MATLAB language environment.The experimental results show that the use of MATLAB in image enhancement processing can result in ideal effectiveness and is of great value to engineering.
