Morphological pattern matching

In this recipe, you will learn how to use the morphological compound operation, hit-or-miss-transform, to find patterns from a binary image. Hit-or-miss transform is a morphological operation that is used to detect a given pattern in a binary image. It uses a pair of disjointed structuring elements to define the pattern to be matched and the morphological erosion operator to implement the pattern matching. The hit-or-miss transform returns a binary image as output in which only those sets of positions are non-zero where the first SE matches and the second SE completely misses the foreground, respectively, in the input binary image.
