title: Implementing imfilter(matlab) with opencv
body: <p>I was trying to implement matlab's imfilter function in opencv. I found across this link which could help me <a href="http://answers.opencv.org/question/8783/implement-imfiltermatlab-with-opencv/" rel="nofollow">CLICK HERE</a>. That link has an answer which I am expecting. But the C++ code there is not complete. As I am new to opencv, I couldnt use the FilterEngine correctly. Anybody help me with the complete code along with the FilterEngine class.</p>
