Frame Hierarchy: A Framework for Level-of-Detail Video Visualization
نویسندگان
چکیده
The advances in video acquisition and storage technologies have increased the quantity and size of the generated video data for various applications. The video data is usually processed by human being as tedious time-consuming task. In this paper we are presenting a novel approach to generate a multiresolution representation of a video data – frame hierarchy – that provides a level-of-detail visualization in an adaptive manner. Frame hierarchy is constructed off-line from the original video data based on a given visual distance metric. At real-time the generated data structure is used to guide the selection of an appropriate levelof-detail representation of the video data based on various control parameters. Frame hierarchy is a general framework for levelof-detail video visualization that supports various navigation patterns and extends the available video visualization techniques. It enables passive visualization as well as interactive visualization where the extracted levels of detail change interactively to comply with the visual error and the user requests.

A Scalable Framework for Information Visualization
This paper describes major concepts of a scalable information visualization framework. We assume that the exploration of heterogenous information spaces at arbitrary levels of detail requires a suitable preprocessing of information quantities, the combination of different graphical interfaces and the illustration of the frame of reference of given information sets. The innovative features of ou...

Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...
