图像处理中的直方图模糊 [英] Histogram blurring in Image Processing

问题描述

我在opencv中使用高斯模糊(平滑)完成了图像模糊处理.我在Google搜索中遇到有关直方图模糊的问题.现在我的问题是，我要对直方图或图像应用模糊处理，而不是重构直方图.

I have done image blurring using Gaussian Blur in opencv (smoothing). I came across in search in Google about histogram blurring. Now my question here is, do I apply blurring to the histogram or to the image and than reconstruct the histogram.

我的感觉是，我将图像应用于图像并制作了直方图，因为对直方图应用模糊处理不会更改图像的任何参数和上下文.好吧，我不确定这是我的原因，但是如果我能就此获得一些建议，将不胜感激.

What I feel is that I apply to the image and than make the histogram because applying blurring to the histogram does not change any parameters and context about the image. Well I am not sure that is my reason but it will be really grateful if I can get some advice on this.

推荐答案

实际上没有什么叫做直方图模糊.您可能指的是直方图均衡或

There is actually nothing called Histogram blurring. What you might be referring to is Histogram Equalization or Adaptive Histogram Equalization. There are many other related techniques if you read up on various papers referenced in the links.

基本思想是-您对直方图应用一维转换，然后将该直方图转移回原始图像；从而将对比度上的所有更改应用到原始图像上.

The basic idea is - you apply a 1D transformation on the histogram and then transfer that histogram back onto the original image; thereby applying all changes on the contrast onto the original image.

希望这会有所帮助.
