| Abstract | Traditional fuzzy c-means (FCM) algorithm, a popular method in data clustering and image segmentation, is known to be sensitive to noise and cluster size, as it does not consider any spatial information and tends to balance cluster populations. FLICM (fuzzy local information c-means) and siibFCM (size-insensitive integrity-based FCM) are two of FCM variation algorithms, each demonstrated effective on overcoming noise or size sensitivity problem. This paper presents a variation of siibFCM, called noise- and size-insensitive integrity-based FCM and denoted as nsiibFCM. Similar to FLICM, nsiibFCM incorporates a local similarity measure based on intensity and purity of each neighboring pixel to remove noise while preserving details, where purity is defined as the normalized difference between the distance from the data point to the center of its assigned cluster and the distance from the data point to its nearest cluster center. Meanwhile, nsiibFCM uses a condition value calculated by using both size and integrity of a cluster, which are presented in siibFCM, to prevent centers of small clusters from drifting toward the adjacent larger and dispersive distributed clusters. Experimental results on both synthetic and real-world images show that our proposed nsiibFCM can effectively partition noisy images with balance- or unbalance-populated and dispersive-distributed clusters. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
