crop the image but keep the dimension same

I am cropping the part of an image using imcrop. Then I am performing some operation on the cropped part and getting coordinates(x and y) from the cropped image. But the coordinates are with respect to the cropped image. Is there a way i can do the operation and get the coordinates based on the original image(not the coordinates of cropped image).

Compute the x and y, or (column and row) of your cropping rectangle, and simply add back in the x and y offset to any coordinates you compute off the cropped image.
