Illumination Invariant Shot Boundary Detection
نویسندگان
چکیده
Illumination variation poses a serious problem in video shot detection. It causes false cuts in many shot detection algorithms. A new illumination invariant measure metric is proposed in this paper. The metric is based on the assumption: the outputs of derivative filters to log-illumination are sparse. Thus the outputs of derivative filters to log-image are mainly caused by the scene itself. If the total output is larger than a threshold, it can be declared as a scene change or a shot boundary. Although this metric can detect gradual transitions as well as cuts, it is applied as a post-process procedure for a cut candidate because an illumination change is usually declared as a false cut.

Shot boundary detection in the presence of illumination and motion
Detection of gradual transition and the elimination of disturbances caused by illumination change or fast object and camera motion are the major challenges to the current shot boundary detection techniques. These disturbances are often mistaken as shot boundaries. Therefore, it is a challenging task to develop a method that is not only insensitive to various disturbances but also sensitive enou...
متن کاملShot boundary detection with mutual information
We present a novel approach for shot boundary detection that uses mutual information (MI) and affine image registration. The MI measures the statistical difference between consecutive frames, while the applied affine registration compensates for camera panning and zooming. Results for different sequences are presented to illustrate the motion and zoom compensation and the robustness of MI to il...
متن کاملA Shot Boundary Detection Technique Based on Local Color Moments in Ycbcr Color Space
Color moments are measures that can be used to differentiate images based on their color. Once computed, these moments provide a measure for color similarity between images. This color similarity can become a measure of finding difference between consecutive frames in a video. Finding the difference between temporally arranged frames in video is one of the issues in shot boundary detection whic...
متن کاملA Divide-And-Rule Scheme For Shot Boundary Detection Based on SIFT
Shot boundary detection is an important fundamental process toward automatic video indexing, retrieval, editing, etc. After a critical review of most approaches seeking to solve this problem, we propose a novel shot boundary detection. To improve the performance of the algorithm and reduce the computational cost, frames that are clearly not shot boundaries are first removed from the original vi...
متن کاملEfficient Video Indexing for Fast-motion Video
Due to advances in recent multimedia technologies, various digital video contents become available from different multimedia sources. Efficient management, storage, coding, and indexing of video are required because video contains lots of visual information and requires a large amount of memory. This paper proposes an efficient video indexing method for video with rapid motion or fast illuminat...
