设置窗口/图片标题

Question

我：

img = imread('pic.jpg','jpg'); 
r = img(:,:,1); 
g = img(:,:,2); 
b = img(:,:,3); 

figure, imshow(r); 
figure, imshow(g); 
figure, imshow(b); 

如何设置标题在每张图片？

Answer 1

您想要更改数字窗口的属性Name。

img = imread('pic.jpg','jpg'); 
r = img(:,:,1); 
g = img(:,:,2); 
b = img(:,:,3); 

figure('Name','this is the red channel'), imshow(r); 
figure('Name','this is the green channel','NumberTitle','off'), imshow(g); 
title(gca,'you can also place a title like this')  

fh = figure; imshow(b); 
set(fh,'Name','this is the blue channel') 

另外，如果你调用imshow(g,[])，它会自动缩放图像以最低/最高。
