In today’s world there is requirement of some techniques or methods that will be helpful for retrieval of the information from the images. Information those are important for finding solution to the problems in the present time are needed. In this review we will study the processing involved in the digitalization of the image. The set or proper array of the pixels that is also called as picture element is known as image. The positioning of these pixels is in matrix which is formed in columns and rows. The image undergoes the process of digitalization by which a digital image is formed. This process of digitalization is called digital image processing of the image (D.I.P). Electronic devices as such computers are used for the processing of the image into digital image. There are various techniques that are used for image segmentation process. In this review we will also try to understand the involvement of data mining for the extraction of the information from the image. The process of the identifying patterns in the large stored data with the help of statistic and mathematical algorithms is data mining. The pixel wise classification of the image segmentation uses data mining technique.
Image enhancement and image segmentation are highly researched topics of Digital Image Processing (DIP). In image segmentation the image analysis is done in various steps and has important role in digital image processing. The fundamental methods and step required to segment the image for gathering information about image using image segmentation will be studied in this work. The most important method for analyzing image is segmentation. In this research work various methods for segmentation will be studied such as-edge detection method, thresholding method, region growing method, clustering method. Similarity and discontinuity are the most important properties of image segmentation algorithm. In the present time the highly growing area in the field of data mining and in the computer vision is image classification. The main purpose of the image classification is to remove space between pixels in the image.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
