User can therefore explore graphically how the basic segments of a video sequence are distributed in the feature space, andĬan recognize and annotate the significant clusters and their structure. Of the considered video sequence are displayed in a Cartesian plane, and the proposed environment offers various functionalitiesįor automatically and semi-automatically finding and annotating the shot clusters in such feature space. The selected features are decided by the user, and can be updated during the navigation session. Moreover, the temporal position and the specific content of each shot can be displayed and analysed in more detail. The basic idea consists in the visualization of a 2D feature space in which the shots of the considered video sequenceĪre located. In this paper, we present an intuitive graphic framework introduced for the effective visualization of video content and associatedĪudio-visual description, with the aim to facilitate a quick understanding and annotation of the semantic content of a video For each category, we present a summary of existing work, highlight the technical aspects of each solution, and compare them against each other. We review more than 40 different video browsing and retrieval interfaces and classify them into three groups: applications that use video-player-like interaction, video retrieval applications, and browsing solutions based on video surrogates. As a result, there are many contemporary research efforts toward developing better video browsing solutions, which we summarize. The ever-growing amount of video content available for human consumption and the inherent characteristics of video data-which, if presented in its raw format, is rather unwieldy and costly-have become driving forces for the development of more effective solutions to present video contents and allow rich user interaction. SVAT CAMERAS CLEAR VU DOWNLOAD PROFESSIONALThere has been a significant increase in activity (e.g., storage, retrieval, and sharing) employing video data in the past decade, both for personal and professional use. We present a comprehensive review of the state of the art in video browsing and retrieval systems, with special emphasis on interfaces and applications.
