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...
Histogram Equalization in Python In this section, I will show you how to implement the histogram equalization method in Python. We will use the above image (pout.jpg) in our experiments. Let's go through the process step by step. The first thing we need to do is import the OpenCV and ...
