Chapter 10 Image Segmentation

Chapter 10 Image Segmentation. Image segmentation divides an image into regions that are connected and have some similarity within the region and some difference between adjacent regions. The goal is usually to find individual objects in an image.

Image Segmentation

Image Segmentation. Introduction. The purpose of image segmentation is to partition an image into meaningful regions with respect to a particular application The segmentation is based on measurements taken from the image and might be greylevel , colour , texture , depth or motion.
