2D Convolution in Python similar to Matlab's conv2

Question

I have been trying to do Convolution of a 2D Matrix using SciPy, and Numpy but have failed. For SciPy I tried, sepfir2d and scipy.signal.convolve and Convolve2D for Numpy. I

Answer 1

Why don't implement it by yourself?, note that conv2 uses a straightforward formal implementation of the two-dimensional convolution equation in spatial form. If a and b are functions of two discrete variables, n1 and n2, then the formula for the two-dimensional convolution of a and b is:

In practice however, conv2 computes the convolution for finite intervals.
