| Abstract | Multi-class pixel labeling is an important problem in computer vision that has many diverse applications, including interactive image segmentation, semantic and geometric scene understanding, and stereo reconstruction. Current state-of-the-art approaches learn a model on a set of training images and then apply the learned model to each image in a test set independently. The quality of the results, therefore, depends strongly on the quality of the learned models and the information available within each training image. Importantly, this approach cannot leverage information available in other images at test time which may help to label the image at hand. Instead of labeling each image independently, we propose a semi-supervised approach that exploits the similarity between regions across many images in coherent image subsets. Specifically, our model finds similar regions in related images and constrains the joint labeling of the images to agree on the labels within these regions. By considering the joint labeling, our model gets to leverage contextual information that is not available when considering images in isolation. We test our approach on the popular 21-class MSRC multi-class image segmentation dataset and show improvement in accuracy over a strong baseline model. |

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.
