摘要
为了在增强对比度的同时又能较好地表现细节,我们提出了一种基于人眼视觉特性的多尺度图像增强方法,该方法在对数域进行图像的高低频分离,并对两部分分量分别进行直方图均衡和局部增强处理。此方法结合了直方图均衡和局部增强算法的优点,增强后的DR图像效果较好。
In order to enhance the image contrast as well as to represent the image details, we propose a new multi - scale contrast enhancement algorithm which separates the low frequency signals and the high frequency signals of the image in logarithmic domain, processes them separately by using HE method and local contrast enhancement. This method integrates HE and local contrast enhancement and finally produces a visually comfortable result image.
