WebThe equations describing this are: Just as in one dimension, shrinking in one domain causes expansion in the other for the 2D DFT. This means that as an object grows in an image, the corresponding features in the frequency domain will expand. The equation governing this is: This is a property of the 2D DFT that has no analog in one dimension.
