Efficient Video Indexing for Fast-motion Video

Due to advances in recent multimedia technologies, various digital video contents become available from different multimedia sources. Efficient management, storage, coding, and indexing of video are required because video contains lots of visual information and requires a large amount of memory. This paper proposes an efficient video indexing method for video with rapid motion or fast illuminat...

Efficient Camera Motion Characterization for MPEG Video Indexing

In this paper, a novel approach to the camera motion analysis is proposed to index videos compressed in MPEG-1 or MPEG-2. Specifically, it fits the motion vectors in MPEG stream into the two-dimensional affine model to detect basic camera operations automatically. The proposed approach involves 1) the construction of motion vector fields (MVFs) by normalizing the types of motion vectors and fil...

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...

Video indexing based on object motion for video-surveillance context

We have developed an algorithm for automatic indexing of video surveillance sequence. The indexing consists in the recognition of specific scenarios defined by a human operator. The principal utility concerns the off-line retrieval of specific behaviour from a long stored image sequence. From a video indexing point of view, image acquisition is made in a favourable condition: fixed acquisition ...

Video Indexing using Motion Estimation

Summarising video data is essential to enable content-based video indexing and retrieval. A novel graph theoretic approach is presented to extract representative key frames corresponding to the shortest path of the graph for each shot. We distinguish further amongst paths of similar weight by examining the standard deviation of their constituent edge weights which improves the distribution of t...
