Inpainting is the art of synthesizing large portions of images using the available background information. Most commonly used inpainting techniques fill the target region or hole in concentric layers from outside inward by sampling values from the background block by block. In each iteration, decisions are made in a greedy fashion taking into account only the local information on the gradient and...
Scene flicker is a common artifact in old archival films. This arises mainly due to aging and causes significant degradation in the perceptual quality of a video. As most of the restoration techniques use temporal information, removal of other artifacts, like blotch, scratch, tearing etc., is highly depended on the consistency of illumination in a video scene. Human vision system is also more sensitive...
Line scratch is a prominent artefact in old films. In this paper, restoration of line scratch is proposed using spatio - temporal video cube. Video is considered as a cube and we assume that t, x and y are three flow directions of frames XY, TY and TX respectively. Vertical and horizontal line scratch is a line of some width in XY frame, but it appears as a rectangular patch in TY or TX frame. Such...
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...
