Mathematical morphology is a theory that was developed in the 1960s for the analysis and processing of discrete images. It defines a series of operators that transform an image by probing it with a predefined shape element. The way this shape element intersects the neighborhood of a pixel determines the result of the operation. This chapter presents the most important morphological operators. It also explores the problems of image segmentation and feature detection using algorithms based on morphological operators.
In this chapter, we will cover the following recipes:
- Eroding and dilating images using morphological filters
- Opening and closing images using morphological filters
- Detecting edges and corners using morphological filters
- Segmenting images using watersheds
- Extracting distinctive regions using MSER
- Extracting foreground...
