| Abstract | TV Commercials play an important role in our lives, and automatic commercial detection is very useful in TV video analysis. Most of previous works focus on visual and audio features of commercial, while ignoring the information of distributions of commercial blocks in different program types and broadcast times. In this paper, we propose a novel method to fuse visual, audio features and global characteristics to detect commercial blocks. Firstly, visual and audio features such as FMPI (Image Frames Marked with Product Information) are utilized to predict the probabilities of commercial shot using SVM classifier. And then, these output probabilities are regarded as observations of a Markov Chain of commercial shots. At last, a viterbi algorithm with time constraints, which are modeled the distributions of duration and inter-arrival time of commercial blocks with GMM (Gaussian Mixture Model), is applied to search the optimal path of commercial shots. Experiments get promising performance on a real TV video database, and show that distributions of duration and inter-arrival time of commercial blocks are good characteristics to capture global feature of commercial blocks. |

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.
