In the previous chapters, you learned various image processing techniques related to image manipulation. In some of them, we concentrated our processing on specific regions of the images, predefined by the user. However, many processes that involve visual media enhancement need to focus on automatically specified regions of interest. In this chapter, we will present some basic techniques for selecting the regions of interest, based on image morphology. We will also revisit the manual selection of regions, presenting some more flexible tools. Then, you will be demonstrated some basic object analysis techniques such as edge, corner, and circle detection. Several examples will help you better understand how morphological operations combined with object analysis methods can help in targeting our processing on specific areas of an image.

In this chapter, we shall:

So, let's start!
