Gaussian kernel in python
WebQuestion: Python Programming Write a script that creates a 2D Gaussian filter and convolves it with an image. - Your code should contain parameters for the size of the filter (number of pixels - nxn) and the standard deviation of the Gaussian kernel. You should be able to change these two variables and create different blurring effects.
