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？
回答：
您要更改图形窗口的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') 另外，如果调用imshow(g,[]) ，它将自动将图像缩放到最小/最大。
