《A new adaptive contrast enhancement algorithm for infrared images based on double plateaus histogram equalization》提出自适应双平台直方图均衡算法,一种基于双平台直方图均衡的红外图像自适应对比度增强算法。 传统的双层斜展直方图均衡化算法使用恒定阈值,不能在不同的场景中改变阈值,使其实际使用是有限的。在提出...
Histogram Equalization (HE) is an effective technique for contrast enhancement. However, the traditional HE method usually results in extreme over-enhancement, which causes the unnatural look and visual artifacts in the processed image. To solve the problem, we propose a novel Modulated Histogram ...

第七步:使用改进的PDF计算每个子直方图的累积密度函数(CDF)。然后使用每个子直方图的CDF计算每个子直方图的映射函数; 第八步:最后,得到了新的增强图像通过结合每个子直方图; 第九步:然后计算每个图像的适应值。这种方法一直持续到满足终止条件或适应度曲线收敛为止。
Adaptive histogram equalization - Wikipedia OpenCV: Histograms CLAHE是全局直方图均衡化的升级版本,CLAHE首先对图片做了分块的操作,也就是划分到多少行,多少列,每一个小块单独做 全局直方图均衡化。但是每一个小块做直方图均衡化,就存在噪声的问题,所以还限制了对比度,也就是对直方图做了裁剪和均衡,直方图上方>某...
For the blurring and unharness of the night image, this paper uses the sharpening method based on Laplace operator to process the image, judge the dark background area by comparing the local gray level, and carry out square equalization and Gamma transformation processing for the local dark back...
Segmentation methods are based on histograms of image gray levels. An example is an image segmentation method combining weighted histogram equalization with adaptive gamma correction for homomorphic filtering73. An improved FCM algorithm based on a given image histogram74. Bonnet et al. proposed to obt...
Gas extraction is an important measure for coal mine gas disaster control. Its effect is closely correlated to the drilling depth. The existing methods usually determine the drilling depth by manually counting the number of drill pipes, and the number of
