3D Visualization of Multiscale Video Key Frames

In this paper, an innovative 3D visualization tool is proposed to facilitate the quickly browsing and understanding of the video sequence for users. Taking advantage of the major windows, our tool presents the multiscale key frames and the video content clearly and effectively. Namely, KF View provides a wonderful navigation of the video key frames with different levels of details. Frame View presents an interesting view of the whole video content. SIM View allows an expressive exploration of the similarities between key frames and also between key frames and the video frames. Importantly, together with many convenient and attractive interactions, this tool is quite efficient to help users grasp the video information soundly.

I. Introduction

Nowadays, digital videos has become an increasing critical factor in many applications. Undoubtedly, a fast and decent understanding of video is highly demanded for practical applications of video browsing. As an important video summarization techniques, key frames are usually applied to represent the most video content, which have attracted much attention in many literatures [1]. Multiscale key frames are also important to better cover the whole information of the video content [2].
