title: Python - Gaussian Kernel for colour images
body: <p>Hello I'm working with images with Python. I want to convolve an image with a gaussian filter.
  The image is an array that it have the shape (64,64,3) 64x64 pixels and 3 channels of colour. How will it be the gaussian filter? which dimension? Do you know a function to define it and make the convolution with the image?</p>
