| Abstract | Face occlusion is a common problem that occurs in applications that analyze images for faces, e.g. detection, tracking and recognition. The presence of occlusion can adversely affect such face processing algorithms. This paper proposes a solution to the problem: we attempt to remove the occlusion by considering it as a damaged part that needs to be regenerated. More precisely, our technique learns the statistical correlation between different regions of the face without enforcing left-right symmetry. However, we learn only from face images that are similar to the target face (i.e. the face dataset is filtered to retain only similar faces). We show that such targeted statistics yield better results than statistics learned from faces in general. The occluded region is then regenerated by predicting its appearance from the most correlated unoccluded region of the same face. We also study how different factors influence our face regeneration technique: the effect of filtering the dataset; the presence/ absence of the target face during learning; the location of the occluded region; and the size of the occlusion. Our work can be used as a pre-processing step for face processing algorithms, or simply to enhance a face image for human viewing. |

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.
