灰度图的直⽅图均衡化（HistogramEqualization）原理与 Python实现 原理 直⽅图均衡化是⼀种通过使⽤图像直⽅图，调整对⽐度的图像处理⽅法；通过对图像的强度（intensity）进⾏某种⾮线性变换，使得变换后的图像直⽅图为近似均匀分布，从⽽，达到提⾼图像对⽐度和增强图⽚的⽬的。普通...
直方图均衡化是一种图像处理方法,用来提高图像的对比度,本博客涉及到直方图的应用PYTHON+OPENCV2 如果一个图像的像素取值范围在很狭窄的一个区域内,那么图像的细节就不是那么的明显,如果可以将图像的像素分布范围均衡化,那么能够提高图像的对比度,如下图所示: 使用python+opencv2计算一幅图像的直方图,图像如下图: 由...
