Paper Abstract

Huge amounts of video data are produced around the world each day. Management is increasingly difficult. Tasks like archiving, browsing, analysis, and search and retrieval are aided by prior automatic temporal video segmentation into shots which are basic units of video. Among the different shot transition types: cut, dissolve, fade and wipe are wipes regarded as difficult to detect because of their variety. This paper presents a new efficient and fast algorithm for wipe detection and position determination. It can be used on the luminance DC coefficients extracted from MPEG sequences in compressed domain or on spatially sub-sampled sequences. With the newly proposed evenness factor the observation that during a wipe spatial zones of change move thru the image can be exploited very well. Wipe candidates are checked with frame differences of frame pairs with certain temporal distances. For the remaining candidates usage of a new approach for the detection of uniform movement of linear zones of change using double Hough transform is proposed. Motion compensation is used to handle local and global motion. The algorithm has a low computational complexity due to its small input data rate and step-wise reduction of wipe candidates.
