| Abstract | In the complex down-looking background, it is difficult to accurately localize various targets because of target deformation and background clutter. In this paper, we develop a target detection algorithm that incorporates bottom-up target segmentation and top-down target recognition. There are two main steps in the algorithm: hypotheses generation (top-down) and hypotheses verification (bottom-up). In the generation step, the study makes an improvement on shape feature, which is more robustness to target deformation. The improved shape feature is used to generate the hypotheses of target locations and figure-ground masks. In the hypotheses verification step, the study firstly computes feasible target segmentation that is consistent with top-down target hypotheses. And then a false positive pruning procedure is proposed. The study also finds the fact that the pruned false positive regions do not align with target segmentation for many down-looking targets. The experimental tasks demonstrate that the algorithm can be high precision and recall with a few positive target-training images and that the algorithm, and be generalized to many target classes. |

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.
