This function returns a cimg wrapped as NumeriMatrix. Contains simplified image reduced to relevant identifying features. Features represent 16 point ring from around each coordinate The x component in the returned cimg represents each coordinate The y component from the returned cimg represents each sample from the 16 point ring
