Abstract | Pedestrian detection is one of hot topics in the field of computer vision and pattern recognition, which is of great value to video surveillance, intelligent traffic and human-computer interaction, etc. and how to improve detection rate and speed is the key. Most traditional pedestrian detection methods are based on the pyramid sliding window scanning method, and for images in which the majority of the region does not contain a body, the detection is inefficient. This study presents a body window sampling algorithm based on binarised normed gradients, which can quickly and effectively extract the window of the image that most likely contains human body to be identified, thus greatly improving the detection speed and obtaining a lower false alarm rate. The authors employ the histogram of oriented gradient feature and the linear support vector machine to train the classifier. For the same false test case in comparison with the pyramid scanning method, when the authors used 2,000 sampling windows for detection, they observed a detection rate increase of 11%, the detection speed increased 19.6 times. For 5,000 sampling windows, the detection rate increased by 20% and the detection speed increased 7.8 times. |

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.
