How to obtain a gaussian filter in python

Question

I am using python to create a gaussian filter of size 5x5. I saw this post here where they talk about a similar thing but I didn\'t find the exact way to get equivalent python c

Answer 1

Using Gaussian PDF and assuming space invariant blur

def gaussian_kernel(sigma, size):
    mu = np.floor([size / 2, size / 2])
    size = int(size)
    kernel = np.zeros((size, size))
    for i in range(size):
        for j in range(size):
            kernel[i, j] = np.exp(-(0.5/(sigma*sigma)) * (np.square(i-mu[0]) + 
            np.square(j-mu[0]))) / np.sqrt(2*math.pi*sigma*sigma)```

    kernel = kernel/np.sum(kernel)
    return kernel
