HDH Based Compressed Video Cut Detection
نویسنده
چکیده
This paper presents a video cut detection algorithm using multi-level Hausdor distance histograms (HDH). Hausdor distance is obtained by comparing edge points of successive frames, wherein the edge information is extracted from compressed frames directly. The use of Hausdor distance histogram instead of the comparison of entering/exiting edge pixel counts [9] makes the algorithm more robust to complicated camera shots. The extraction of edge information in compressed domain greatly escalates the cut detection process, which is critical for indexing of large amount of video materials in large scale video databases. The performance of this algorithm has been tested on a variety of videos. The experimental results show that this algorithm can robustly tolerate rapid changes in scene brightness as well as multiple object and camera motions.

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملTools for Compressed-Domain Video Indexing and Editing
Indexing and editing digital video directly in the compressed domain offer many advantages in terms of storage efficiency and processing speed. We have designed automatic tools in the compressed domain for extracting key visual features such as scene cut, dissolve, camera operations (zoom, pan), and moving object detection and tracking. In addition, we have developed algorithms to solve the dec...

As content based video indexing and retrieval has its foundations in the prime video structures, such as a shot or a scene, the algorithms for video partitioning have become crucial in contemporary development of digital video technology. Conventional algorithms for video partitioning mainly focus on the analysis of compressed video features, since the information relevant to the partitioning p...
متن کاملReal-time shot-cut detection in a compressed domain
In this short paper, we propose a fast and simple shot cut detection algorithm, which directly operates in compressed domain and suitable for real-time implementation. The proposed algorithm exploits the existing MPEG techniques by examining the prediction status for each macro-block inside B frames and P frames. As a result, locating both abrupt and dissolved shot cuts is operated by a sequenc...
متن کاملVideo Abstraction in H.264/AVC Compressed Domain
Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...
