Imresize3 not resizing in z direction?

7 views (last 30 days)
Hello,
I was using imresize on a stack of 54 images (each 2350 by 2350) forming a 3d array.
the pictures are binary. I also tried with grayscale.
I tried it like this:
stackresized = imresize3(stack, [NaN NaN 9 ]);
which crashed matlab.
I tried
stackresized = imresize3(stack, 0.2)
Which worked, but only in x and y directions. the number of slices remained the same.
Edit: I was mistaken, it used simply just one slice at a time from the array in the second example. When i feed it the whole array, the error is "Input image must have three dimensions but instead has 4 dimensions."
Which is strange because it is a grayscale 0-255, one colour channel of a RGB stack. should be 3 dimensional.
Can someone explain what I'm doing wrong here?
Thanks.

The second method should work. Are you sure you used imresize3() and not imresize() for that?
For the first method, input all three desired dimensions, even if they don't change from the original.

Try
squeeze(stack)
to remove the third (size 1) dimension. Or,
stack = squeeze(RGBstack(:,:,1,:));
