M. Julius Hossain

You can try imresize

B = imresize(A, scale, method)

Shumoos Al-Fahdawi

Thanks for your answer M. Julius. I want to ask you this function affect on the resolution of image???. I've got anther function but it just work on matlab14 and this function keep of resolution

hgs=vision.GeometricScaler;

hgs.ResizeFactor;

hgs.InterpolationMethod='Bilinear';

J = step(hgs,I);

imshow(I); title('Original Image');

figure,imshow(J);title('Resized Image');

In terms of resolution they are same. ‘step’ will provide you greater flexibility such as to define roi etc. Anyway you will not be able to see greater detail of an image just by scaling it up.

Thanks for your answer. this answer help me more
