摘　　要：针对红外弱小目标图像的特点,本文提出了一种新的增强算法。该算法首先通过设置平台阈值对背景的增强进行抑制,然后将直方图在灰度密度和灰度间距两个方向进行均衡处理。该算法简洁,实时性强,图像增强效果好。In this paper, a new enhancement algorithm is presented based on the characters of infrared dim-small target images. At first, the image background is suppressed by setting a threshold. Then, both gray density and gray interval of the histogram are equalized. This algorithm has the features of small calculation, excellent image enhancemcnt and real-time performance.
