Video shot detection based on linear prediction of motion
نویسندگان
چکیده
This paper describes an approach for video shot detection. It relies on the temporal analysis of frame to frame optical flow measurements. These measures, which are motion wavelet coefficients directly estimated from image sequence, exhibit discontinuities when shot boundaries occur. These transitions are detected by considering the temporal trajectories of the linear prediction errors of wavelet coefficients. Experimental results and performance evaluation using videos with reference segmentations are presented to demonstrate the efficiency of the approach.

Semantic Analysis of Basketball Video Using Motion Information
This paper presents a new method for extracting semantic information from basketball video. Our approach consists of three stages: shot and scene boundary detection, scene classification and semantic video analysis for event detection. The scene boundary detection algorithm is based on both visual and motion prediction information. After the shot and scene boundary detection, a set of visual an...
متن کاملShot Boundary Detection Using Macroblock Prediction Type Information
The increasing availability and use of digital video has led to a high demand for efficient video analysis techniques. The starting point in video browsing and retrieval systems is the low-level analysis of video content, especially the segmentation of video content into shots. In this paper, we propose a method for automatic video indexing based on the macroblock prediction type information of...

متن کاملTraffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
