ON IMAGE SEGMENTATION TECHNIQUES

Digital image processing supports strong research program in areas of image enhancement and image based pattern recognition.Among the various image processing techniques image segmentation plays a vital role in step to analyze the given image. Image segmentation is the fundamental step to analyze images and extract data from them. This work deals on the basic principles on the methods used to segment an image. Segmentation has become a prominent objective in image analysis and computer vision. To segment the images, from segmentation techniques edge detection, thresholding, region growing and clustering are taken for this study. Segmentation algorithms are based on two properties similarity and discontinuity. This paper focuses on the various methods that are widely used to segment the image. I. INTRODUCTION Digital image processing is having many recent applications in the fields of remote sensing, medicine, photography, film and video production, security monitoring. New innovative technologies are emerging in the fields of image processing, especially in image segmentation domain.
