一种红外图像增强的新方法

A new approach to IR image enhancement

针对红外图像增强问题 ,提出利用双门限分割后再进行灰度变换的图像增强新方法 ,将图像按两个灰度阈值分割成 3部分 ,即灰度值的高段、中段和低段 .对 3部分采用不同的灰度变换方法 ,以求得到最佳的视觉效果 .实验结果表明该方法效果很好 .

This paper describ es a new approach to IR image enhancement, which operates a gray-value transfor m in terms of a bi-threshold segmentation. The pixels of an image will be segme nted to three sections, named high section, middle section and low section. For the best result of vision, different transforms will be taken for different sect ions. The experimental result is given in detail.
