| Abstract | Image segmentation is the process of partitioning a digital image into multiple segments. Image segmentation is typically used to locate objects and boundaries (points, lines, curves, etc.) in images. Segmentation is an important part of many automated image recognition systems. The goal of segmentation is to simplify and/or change the representation of an image into units that are easier to analyze. It is the process of assigning a label to every pixel in an image such that pixels with the same label share certain visual characteristics. A histogram based image segmentation method is presented which divides the whole image into sub regions based on two mean values. The means are computed based on a preset threshold value calculated using Otsu's method, which is dependent on the intra class variance and class probability. Based on the mean values and the threshold, the image histogram is divided into three classes, LowIntensity, HighIntensity and unknown class. The unknown class can be further subdivided to these three classes based on modified means calculated using modified threshold.. This process continues until no further subdivision based on mean values is possible. Finally, all the respective class regions are merged. The method better identifies fine structures of objects in complex images. The computational cost is found to be low for this method as the iterative method consumes reduced computational time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
