The objective of video segmentation is to segment a video sequence into parts called shots corresponding to a continuous set of frames taken from one camera. Transitions between shots can be abrupt (cuts) or gradual. Abrupt transition can be easily detected while detection of gradual transition, such as dissolve, in still an unsolved problem. In this paper we present a novel approach for a reli...

Metal films are known to dissolve crystalline semiconductors at temperatures well below the eutectic temperature. Dissolution and transport of common semiconductors in contact with Au films have been demonstrated at room temperature. 1 The solid AI metallization used in electronic devices is known to dissolve troublesome quantities of crystalline Si after heat treatment at 400oC.2 Metal films a...

There are a number of shots in a video, each of which has boundary types, such as cut, fade, dissolve and wipe. Many previous approaches can find the cut boundary without difficulty. Ho wever, most of them often produce false alarms for the videos with large motions of camera and objects. We propose a shot boundary detection method combining Bayesian and structural information. In the Bayesian ...

A video stream consists of a number of shots each of which has different boundary types such as cut, fade, and dissolve. Many previous approaches can find the cut boundary without difficulty. However, most of them often produce false alarms for the videos with large motions of camera and objects. In this paper, we demonstrate that the shape of the histogram difference between two successive col...

TRECVID (TREC Video Retrieval Evaluation) is sponsored by NIST to encourage research in digital video indexing and retrieval. It was initiated in 2001 as a “video track” of TREC and became an independent evaluation in 2003. AT&T participated in three tasks in TRECVID 2006: shot boundary determination (SBD), search, and rushes exploitation. The proposed SBD algorithm contains a set of finite sta...

We present improved algorithms for automatic fade and dissolve detection in digital video analysis. We devise new two-step algorithms for fade and dissolve detection and introduce a method for eliminating false positives from a list of detected candidate transitions. In our detailed study of these gradual shot transitions, our objective has been to accurately classify the type of transitions (f...
