matlab中两个彩色图像的直方图匹配 [英] Histogram matching of two colored images in matlab

问题描述

任何人都知道如何在两个彩色图像上执行RGB直方图匹配？

例如这是一个要重新映射的图像：

这是一个目标图片

然后RGB重新映射的图像看起来像这样

这是我到目前为止所做的，在这段代码中我采用了两个彩色图像 im1 和 im2

我拿了 im1 哪一个必须重新映射然后分解成

它的颜色然后我采用了每种颜色im1并使用 histeq 将他们的直方图与<$ p

im2中的每种颜色相匹配。

我不知道如何从颜色重建重新映射的图像我匹配，任何帮助请，这将是不错的??：

  im1 = imread（'Atlas-Mer.png'）; 
 im2 = imread（'techno-trs.png'）; 
 
 Red1 = im1（：，：，1）; 
 Green1 = im1（：，：，2）; 
 Blue1 = im1（：，：，3）; 
。 
。 
。 
 Red2 = im2（：，：，1）; 
 Green2 = im2（：，：，2）; 
 Blue2 = im2（：，：，3）; 
 
 red2n = histeq（Red2，HnRed1）; 
 green2n = histeq（Green2，HnGreen1）; 
 blue2n = histeq（Blue2，HnBlue1）; 
  

解决方案

你可以这样做：

  im2（：，：，1）= red2n; 
  

等。

Anyone knows how to perform RGB histogram matching on two colored images?

for example this is an image to be re-mapped:

and this is a target image

Then the RGB remapped image look like this

here is what I did so far, in this code I took two color images im1 and im2

I took the im1 which is the one that has to be remapped then broke it up into

its colors then I took each color of im1 and used histeq to match their histograms to

each color in im2.

I don't know how to reconstruct the re-mapped image from the colors I matched, any help please that would be nice??:

im1 = imread('Atlas-Mer.png');
im2 = imread('techno-trs.png');

Red1 = im1(:, :, 1);
Green1 = im1(:, :, 2);
Blue1 = im1(:, :, 3);
.
.
.
Red2 = im2(:, :, 1);
Green2 = im2(:, :, 2);
Blue2 = im2(:, :, 3);

red2n = histeq(Red2,HnRed1);
green2n = histeq(Green2,HnGreen1);
blue2n = histeq(Blue2,HnBlue1);

解决方案

You can just do:

im2(:, :, 1) = red2n;

etc.
