| 摘 要： | 针对直方图均衡化算法无法有效抑制噪声的缺点,提出了一种新的自适应红外图像增强算法。首先统计红外图像直方图,估计出平台阈值,然后对统计直方图进行修正,最后校正图像中所有像素灰度值并进行输出。结合实际应用,搭建了高速红外图像增强处理平台。基于该平台用真实图像验证了提出的算法,实验结果表明,本系统在提高对比度的同时,有效地抑制了噪声的干扰,获得了较好的增强效果,算法运行时间小于20ms,能够满足工程项目的实时性要求。

| Abstract: | According to the disadvantage of the large noises of histogram equalization algorithm, a new adaptive image enhancement algorithm is presented.Firstly, the statistical histogram of the infrared image is proposed.Then, the threshold of plateaus equalization is calculated and the statistical histogram is modified.Finally, the bright value of the pixels of the image is changed.An embedded high speed image enhancement processing system is designed according to the need of the practical application.Experimental ... |
