Block based image segmentation

Abstract

Image segmentation is an important research field due increasing Internet and computer based applications and also for video coding but it is very challenging. There exist a huge number of algorithms for image segmentation using split and merge having some limitations for which pattern based object segmentation using split and merge (PSM) was proposed to overcome the problems of basic split and merge (SM) algorithm being unable to segment properly all types of objects in an image due to huge variations among the objects. Addressing this issue, a new algorithm namely block based image segmentation (BIS) algorithm has been presented in this paper considering multi stage merging technique. The experimental analysis proves the superior performance over the existing algorithm. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
