Abstract | In this paper, we present a novel approach to achieve diagnostic color estimation for histological objects in pathology images. The method is based on a von Mises mixture model for hue histogram, followed by implicit pixel clustering via maximum likelihood estimation and representative color computation. Unlike conventional approaches adopting linear processing algorithms to analyze hue histogram which is characterized by a nature of periodicity, we build a circular cluster model composed of multiple von Mises distributions to address the directional nature of hue. Experimental results on synthetic circular data suggest that the proposed circular model outperforms both classical linear thresholding methods and the state-of-art circular thresholding approach in terms of cluster parameter estimation. The color estimation experiment on publicly-accessible cytopathology images demonstrates that our method is capable to accurately estimate object's diagnostic color, which can be used for subsequent image analysis. |

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.
