設置窗口/圖片標題

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); 

如何設置標題在每張圖片？

Answer 1

您想要更改數字窗口的屬性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，如果你調用imshow(g,[])，它會自動縮放圖像以最低/最高。
