Hi,
I have an image and i did FFT to the image. To see the image I used imshow(im,[]). But I want to use imcrop function in the the FFT image. The issue is the while image show to me when I run the code. I know I have to add [] in imshow(im,[]) to show all the pixels but how I can see all the pixels when I use imcrop function
I tried abs / log to imcrop but still does not show me the FFT as in imshow function shows.

Use rescale() of the data before cropping.
