title: The equivalent function of Matlab imfilter in Python
body: <p>I know the equivalent functions of  <code>conv2</code> and <code>corr2</code> of MATLAB are <code>scipy.signal.correlate</code> and <code>scipy.signal.convolve</code>. But the function <code>imfilter</code> has the property of dealing with the outside the bounds of the array. Like as <code>symmetric</code>, <code>replicate</code> and <code>circular</code>. Can Python do that things</p>
