用另一种颜色Matlab替换图像中的某个颜色范围 [英] Replace a certain color range in an image with another color Matlab

问题描述

如何替换具有特定RGB范围的像素，而不仅仅是此

how to replace the pixels having a certain RGB range not just a specific value as shown in this question like for example pixels with R ranging from 140-150, G ranging from 50-55 and B ranging from 61-70 , with another single value like (150,57,80). If anyone could please advise.

推荐答案

这也是对您在先前发布的另一个问题中提供的答案的修改.您只需更改logical蒙版计算，即可搜索一系列红色，绿色和蓝色值.

This is also a modification to the answer I provided in the other question you posted earlier. You simply change the logical mask calculations so that we search for a range of red, green and blue values.

因此:

red = A(:,:,1); green = A(:,:,2); blue = A(:,:,3);

%// Change here
mred = red >= 140 & red <= 150; 
mgreen = green >= 50 & green <= 55; 
mblue = blue >= 61 & blue <= 70;

%// Back to before
final_mask = mred & mgreen & mblue;
red(final_mask) = 150; green(final_mask) = 57; blue(final_mask) = 80;
out = cat(3, red, green, blue);
