Morphological Operations

8.1 Introduction

So far, we have discussed the various methods for manipulating individual pixels in the image through filtering, Fourier transform etc. An important part of image analysis involves understanding the shape of the objects in that image through morphological operations. Morphology means form or structure. In morphological operations, the goal is to transform the structure or form of the objects using a structuring element. These operations change the shape and size of the objects in the image. Morphological operations can be applied on binary, grayscale and color images. We omit color morphology in this chapter, as most bio-medical images are grayscale or binary images. We begin with basic morphological ...
