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 morphology on color images in this chapter, as most bio-medical images are grayscale or binary images. We begin ...
