Trouble with rotating an image and saving it with different rotation angles.

Hi,

I am trying to rotate an image and save a set of the rotated images with different rotation angles but having this error: "Unable to perform assignment because the left and right sides have a different number of elements". Below is the code I tried so far. Can someone extend a hand of help, please?

I = imread('shale.png');

a = 1:4:360;

for i = 1:length(a)

K(i) = imrotate(I,a(i),'bilinear','crop');

end

You should try

K(numberOfRowsInImage,numberOfColumnsInImage,i) = imrotate(I,a(i),'bilinear','crop')

K(i) is just vector of size i so you can not asign whole image in such vector.

Thanks for this but still not working.

ok i think i can see the problem. Your image is RGB image so it has size numOfRows x numOfColums x 3. Try this:

I = imread('shale.png');

a = 1:4:360;

for i = 1:length(a)

K(:,:,:,i) = imrotate(I,a(i),'bilinear','crop');

end

Well, this does not too.
