I rotate an image at a particular angle and then find its mean and max value. How do I display the mean and max image as shown in the 2nd and 3rd columns of the link below?
The column 1 - is the rotated image at an angle,
column 2 - mean
column 3 - maximum
Please, can someone help me how to display the mean and max images as in the 2nd and 3rd column of the link?

max_img = max(Img(:));

You might need to reassign the columns with the mean and max values you have computed

It looks like this came from a paper. Didn't they describe how to get the images in the second and third columns? Is the second image the mean of the image as if you had rotated at a certain number of angles? Like 0 - 90 or something? Can you just use cart2pol(), then get the mean or max along columns, then invert with pol2cart()?
