Image Segmentation
CHAPTER OBJECTIVES
- To discuss segmentation as an important step in image processing applications.
- To discuss isolated points and line detection.
- To explain the use of gradient and Laplacian operators to detect edges in the image.
- To discuss various ways in which a closed boundary of an object is formed.
- To analyse region oriented and thresholding segmentation.
- To illustrate the use of motion in segmentation.
6.1 INTRODUCTION
Image analysis is an area used for extracting the information from an image. Before we extract the information, the image has to be subdivided into constituent parts or objects. The process of subdividing the given image into its constituent parts or objects is called image segmentation. ...
