An Algorithm for Wipe Detection
نویسندگان
چکیده
The detection of transitions between shots in video programs is an important rst step in analyzing video content. The wipe is a frequently used transitional form between shots. Wipe detection is more involved than the detection of abrupt and other gradual transitions because a wipe may take various patterns and because of the diiculty in discriminating a wipe from object and camera motion. In this paper, we propose an algorithm for detecting wipes using both structural and statistical information. The algorithm can eeec-tively detect most wipes used in current TV programs. It uses the DC sequence which can be easily extracted from the MPEG stream without full decompression.

A Robust Wipe Detection Algorithm
In this paper, we present an improved wipe detection algorithm by analyzing spatio-temporal slices of videos. The algorithm is based on the observation that the regional boundaries of various shapes in spatiotemporal slices give rise to different wipe patterns. Wipes can be detected by locating these boundaries. Our algorithm thus exploits the structural and color information in slices to detec...
متن کاملEffective wipe detection in MPEG compressed video using macro block type information
For video scene analysis, the wipe transition is considered most complex and difficult to detect. In this paper, an effective wipe detection method is proposed using the macroblock (MB) information of the MPEG compressed video. By analyzing the prediction directions of B frames, which are revealed in the MB types, the scene change region of each frame can be found. Once the accumulation of the ...
متن کاملWipe Scene Change Detection in Video Sequences
This paper presents a novel algorithm for wipe scene change detection in video sequences. In the proposed scheme, each image in the sequence is mapped to a reduced image. Then we use statistical features and structural properties of the images to identify wipe transition region. Finally, Hough transform is used to analyse the wiping pattern and the direction of wiping. Results show that the alg...

Contamination with radiopharmaceuticals in nuclear medicine centers in addition to being a health concern requires time-consuming decontamination efforts. According to NRC (Nuclear Regulatory Commission) contamination should be monitored in nuclear medicine centers where radiopharmaceuticals are prepared and administrated at the end of each working session; otherwise, contamination spread...
متن کاملA multi-resolution video segmentation scheme for wipe transition identification
This paper presents a new methodology for wipe transition identification.Shot transition detection is an important technique for making videos easier to handle. Due to the wide variety, wipe transition appears to be the most difficult one to be detected among all types of shot transitions. We propose an approach that takes advantage of the production aspect of video. Each video frame is first d...
