设置窗口/图片标题

Question

我有：

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

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

如何在每张图片上设置标题？

Answer 1

您想要更改图窗口的Name - 属性。

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')

此外，如果您致电imshow(g,[])，它会自动将图片缩放到最小/最大。
