摘要
视频监控系统在光线不足的环境下容易导致视频模糊,图像不清晰,为了实现更好的图像效果,提出一种实时低照度彩色图像增强方法,通过色彩空间转换、直方图均衡处理和线性变换等方法,对低照度的彩色视频图像进行实时增强处理,扩展图像动态范围,提高对比度,提高视频图像的可视效果。
In the environment of insufficient light,vedio monitoring system could be easy to get indistinct vedios and blurred pictures.In order to achieve better image effect,a real-time low illumination color image enhancement method is proposed.By means of color space conversion,histogram equalization and linear transformation,the low illumination color video image is enhanced in real time,the dynamic range of the image is expanded,and the contrast and the visual effect of the video image are improved.
