Several algorithms have been proposed to solve the problem of camera motion estimation in digital videos. However, the distinction between translation along the x-axis (y-axis) and rotation around the y-axis (x-axis) has only rarely been considered, and no approach of this kind is known to us for the MPEG domain. In this paper, we present such an algorithm(More)
—The video coding standard H.264 supports video compression with a higher coding efficiency than previous standards. However, this comes at the expense of an increased encoding complexity, in particular for motion estimation which becomes a very time consuming task even for today's central processing units (CPU). On the other hand, modern graphics hardware(More)
In recent years, many features have been suggested to facilitate the task of video retrieval. However, up to now, three-dimensional (3D) scene information has not been utilized to retrieve shots from a database consisting of monocular video sequences. In this paper, we propose the use of depth features for video retrieval purposes. Our depth feature(More)
