Automatic image retrieval similar to a query image is an important task in computer vision. To obtain this goal, every image in database needs to be modeled. A signature is learned for each image and stored. A sparsity based image content modeling and retrieval is proposed in this paper. Sparsity based data modeling has been successfully applied across various areas of image processing. A dictionary...
Video Summarization is a promising approach towards concatenating the moving patterns of objects into a single image. The summary attracts readers because of less browsing time, minimized spatio-temporal redundancy, and a feel of motion activity of the scene. It becomes crucial when video uncovers multiple interacting objects and the quality of the video summary in the form of resolution deteriorates...
Wide area surveillance requires high-resolution images of the object of interest derived possibly from only low-resolution video of the whole scene. We propose a combined tracking and resolution enhancement approach that increases the resolution of the object of interest during tracking. The key idea is the use of an object-specific 3D mesh model with which we are able to track non-planar objects...
