| Abstract | In this paper, we propose a method to construct an accurate traffic sign detector with a small number of manual interactions. When using a statistical learning approach, a huge number of training samples should be prepared for constructing an accurate detector. However, in a real environment, traffic signs have various appearances, and their backgrounds vary widely, too. Therefore, it is very difficult and expensive to manually collect all possible views. Co-training is one of the semi-supervised learning techniques, that can collect training samples efficiently and automatically by using multiple classifiers. In this paper, we employ this approach for improving the accuracy of a traffic sign detector with low cost. The main contributions of this paper are the extension of the co-training method by introducing a majority voting scheme, and the introduction of this framework for improving the accuracy of traffic sign detection. By using this voting type co-training, the proposed method gathers traffic sign samples automatically and accurately, and improves the performance of the traffic sign detector. Experimental results showed that the proposed method improved the accuracy of the detector with a maximum F-measure of 0.95 from 0.72. |

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.
