As human vision system (HVS) is highly sensitive to motion, motion saliency is an important field of research in video signal processing. But, HVS is particularly insensitive to subtle motions with low amplitude. Though, in many practical fields, e.g., biomedical science, earth science, plasma science etc., these low amplitude motions are significant for predicting certain crucial events, most of...
In vision based applications, depth plays a crucial role from different aspects. From 3D rendering to automation, precision in depth measurement is important for acceptable performances. Though several techniques have been proposed to capture depth map of a scene, the estimation is either erroneous or much expensive for regular usage. Thus, the demand for high accuracy depth measurement is prominent...
Denoising a video data is one of the well-known problems in the field of video processing. The problem is still drags focus of researchers due to its relevance in data transmission, video display and other machine vision applications. Though, several algorithms are proposed for denoising a video, most of them denoise it frame by frame considering the spatial information present in a scene. The algorithms,...
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...
Video decomposition into visually similar part and feature part has gained considerable importance due to its applications in different fields of video processing. Some of the diverse problems that can be handled using this decomposition technique are- background estimation, motion saliency detection, single object tracking, multiple object tracking, artifact detection, compression and various others...
With the increasing usage of visual media, it is becoming difficult to store, search and manage them properly due to their large data size. Sorting a video manually is a tedious work and does not produce efficient results. Thus it is becoming absolutely necessary to invent modern techniques that can minimize the effort of the user by summarizing the content of a video in an effective way such that...
