How to increase image size while keeping image sharp?
显示 更早的评论
Hi everyone,
This is a pretty general question. I took a screenshot of the MATLAB toolstrip (actually part of it).
It looks great except I want it bigger. So I use imresize( ),
B = imresize(A, 4);
but it looks pixelated.
Is there a better way to do this?

You need to use the nearest option:
B = imresize(A, 4, 'nearest');

I don't think you should use sharpen after it. That might introduce noise. The nearest option should give edges just as sharp as in the original, the only thing is it might give you jaggies that didn't exist in the original (because you magnified it so there are now more pixels).

Yes, it can be, which is good for me because that's my whole career and it's good if people think it's hard because they are impressed with my work.
Post your original image if you want.
