Let’s use skimage module for the read operation and display the image using matplotlib module. This function is a wrapper around scipy.ndi.gaussian_filter(). the Prewitt operator is not completely rotation invariant. Default For integer images, the above equality holds to within one; for floating- Only 3 channels are supported. processing. Electronic Imaging, 13(1): 146-165, Yen J.C., Chang F.J., and Chang S.
