| Abstract | Current trademark classification procedure adopts the Vienna approach developed by World Intellectual Property Organization (WIPO). It has the following drawbacks. 1) Tremendous amount of human efforts are required to classify and annotate each trademark submitted for registration; the time required to complete the registration would increasing as the number of registered trademarks increases. 2) Same trademark may be classified into different classes by two human classifiers. 3) It is difficult to classify trademarks with abstractive contents by human classifier. For the above reasons, it is important to improve the existing trademark classification system by replacing human classifier with effective and precise computer algorithms. As we review previous researches on trademark indexing and retrieval, we find that shape information together with profile and contents of trademark plays an important role in determining the trademark similarity. In this paper, we develop an effective feature for trademark image using block feature index (BFI), the concept is borrowed from vector quantization. For performance evaluation purpose, 3000 trademark images in MEPG-7 were classified into 10 categories for experiments. We compare the recall rate and precision for the proposed BFIC algorithm and two well-known methods: Hu's 7 moments (H7M) and Zernike moments (ZKM), the proposed BFIC method outperforms the other two methods. The performance can be even better by cascading the proposed BFIC and ZKM. |

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.
