MATLAB: Error in resizing 3d image

Question

I have a dataset of 3d images containing 30 images of different sizes,I want to resize all images to a paricular size

for example for 2d if we use imresize(I,[25 256]) all images in dataset will be resized

same way i tried for 3d using

J = resize(I,size(I).*[0.3 0.3 1])

but it is not reduced to a particular size,i need all images to have same size

say 256x256x3

please help

Answer 1

If it's a color image (as opposed to a volumetric image, as from CT or MRI), you do it exactly the same way as for a gray scale image. No difference at all in the arguments to imresize.

rgbImage256 = imresize(rgbImage, [256 256]);
