Abstract | Most of the correlation filter (CF)-based trackers utilise the circulant structure of the training samples to learn discriminative filters to identify the tracked target, which has shown excellent performance in terms of both tracking accuracy and speed. However, CF-based trackers possess two potential drawbacks: the search regions are limited to the small local neighbourhood for the high-speed tracking purpose; thus, they usually have very few context information and tend to drift from a target in extreme attributes, e.g. background clutter, large-scale variation, and fast motion. Another is that once the tracking target is lost under large displacement motion, it cannot be re-identified in subsequent frames. In this study, the authors propose a unified tracking-and-detection framework with distractor-aware (UTDF-DA), which involves both context learning and target re-identification with a target-aware detector to solve the drawbacks mentioned above. They first incorporate the distractor constraint as context knowledge into a continuous correlation filter for distractor-aware filter learning. Then a single-shot multibox detector-based target-aware detector is trained by domain-specific meta-training approach for deep detection features and hard-negative samples generation. Moreover, they propose the spatial-scale consistency verification method for the target re-identification task. Compared with existing state-of-the-art trackers, UTDF-DA (the authors’) tracker can achieve improved tracking performance in terms of both accuracy and robustness; they demonstrate its effectiveness and efficiency with comprehensive experiments on OTB-2015, VOT-2016, and VOT-2017 benchmarks. |

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.
