In this chapter, we presented several useful morphology-based techniques for selecting regions of interest and masking an image. After visiting several examples based on the morphology theory, we also provided an introductory presentation of some powerful object analysis tools that can be used for several image processing applications such as image enhancement, object detection, image registration, and so on. The focus of this chapter was on hands-on, practical examples demonstrating the significance of the methods presented. More specifically, in this chapter we covered:
What binary images are and how we can create them using automatic thresholding techniques.
How we can refine a region of interest to better suit our needs, using dilation (
imdilate) and erosion (imerode) to perform enlargement and shrinking, respectively.What structuring elements are and how they affect the quality of dilation and erosion results.
What masking is and how we can use it to process specific regions of...
