This code snippet generates random phase values between 0 and 2π for an M × N sized image and multiplies it with the image1 array element-wise. This operation results in a phase shift of the complex values in the image1 array.
The multiplication with the exponential of the phase shift rotates the complex values in the image1 array clockwise or counterclockwise depending on the sign of the phase values. This operation is useful in image processing tasks such as image registration, where phase shifts can be used to align two images.
Overall, this code snippet applies random phase shifts to the image1 array, which can introduce some noise or distortions in the image. However, it can also be useful in certain applications where phase information is important.
