Hello!

I want to resize the image to 50x50 pixels. Then I show it in an axes(I have a user interface and axes placed on my interface), but it does not seem normal -- the resized image lost its resolution.

This is my code:

image = imread('2.jpg');
resizeIm = imresize(image,[50 50]);
axes(handles.axes1);
imshow(resizeIm);

Please see the the two images I attached. You will know.

Thanks

How big was the original? Of course it's going to lose resolution if you remove pixels (i.e. 50x50 is smaller than what you started with).

If you don't want a loss of resolution, the solution is to not reduce the size. If you reduce the size, you're going to reduce the resolution - there's no way around it.
