title: OpenCV : How do I find the minimum element along a specific dimension?
body: <p>I'm a new user to OpenCV. I'm using version 2.3.2 (from the SVN repository). 
  I have a specific 3-dimensional <code>cv::Mat</code> structure which is 288 x 384 x 10. This represents a 288 x 384 image and the other 10 channels represent a disparity value. I want to find the minimum element and its location. There is a <code>minMaxElem</code> function in OpenCV with it doesn't work with multi-dimensional arrays. Any idea how I can use the channel splitting functions in OpenCV to perform this?</p>
