| Abstract | This paper proposes a text-independent writer identification framework for online handwritten text. The method utilizes an unsupervised learning scheme termed `subtractive clustering' to discover the unique writing styles of a given author. Subtractive clustering has been adopted in the literature for the problems of image segmentation and speaker identification. To the best of our knowledge, its applicability in the domain of writer identification is yet to be explored. Unlike traditional clustering techniques such as k-means and fuzzy c-means, the subtractive clustering algorithm does not rely on the initial choice of seed points. Instead, it locates the high density regions in the feature space, and this make this scheme an interesting exploration to capture the writing styles of an author (referred to as `prototypes'). The discovered prototypes from the clustering algorithm are subsequently employed to score the authorship of an unknown handwritten text. In addition, inspired from the t f-idf approach used in document retrieval, we propose a modified scoring scheme for identifying the writer. The efficacy of the algorithms are evaluated on the paragraphs from the IAM-Online Handwritten Database. |

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.
