Abstract

Besides the two primary operations of erosion and dilation, there are two secondary operations that play key roles in morphological image processing, these being opening and its dual, closing. We focus mostly on opening, the properties of closing usually being analogous via complementation. Although opening is defined in terms of erosion and dilation, it possesses a more geometric formulation in terms of structuring element fits that is the basis for its application.
