可见光目标检测中图像增强方法研究

文中对目前常用的图像增强技术进行了研究,首先对目标图像特性进行了分析,介绍了常用的滤波方法,包括中值滤波、高通滤波和winner滤波等方法,用这些方法对给定的图像进行了滤波;接着提出了一种和最大值滤波的图像增强方法,也用该方法对给定的图像进行了滤波,并比较了各种方法处理图像中对目标信噪比的改善情况,给出了相应的结果,结果表明和最大值滤波要优于其他的方法。

Image Enhancement Technology in the Target Detection of Visible Light

This paper studies the image enhancement technology in common use nowdays.The paper first analyzes the characteristics of the target image, and introduces the common filter methods, including medium-pass filtering, high-pass filtering and winner filtering,which are used to filter the given image, and thus proposes a maximum summation filtering image enhancement method ,which is also used to filter the given image. The comparisons of all the methods for the improvement of target Signal Noise Ratio in the process of image are also presented. The results indicate that the maximum summation filtering method is much better than the others.
