Gradual scene change detection using Cut frame difference and Dynamic threshold

Dynamic threshold method for scene change detection

In general, the scene change for video indexing could be detected by using an appropriate threshold. However, the single fixed threshold value used in previous researches cannot perform well for all videos equally. In this paper, we propose a dynamic threshold method(DTM) in order to improve the performance of the scene change detection. The proposed method utilizes variable parameters obtained...

Scene Change Detection for H.264 Using Dynamic Threshold Techniques

Several scene-change detection algorithms have been proposed in literature up to now. Most of them use fixed thresholds for the similarity metrics used to decide if there was a change or not. These thresholds are obtained by empirically or they must be calculated before the detection after the whole sequence is obtained. Performance of most scene change detectors decreases considerably for vide...

Video Cut Detection using Frame Windows

Segmentation is the first step in managing data for many information retrieval tasks. Automatic audio transcriptions and digital video footage are typically continuous data sources that must be pre-processed for segmentation into logical entities that can be stored, queried, and retrieved. Shot boundary detection is a common low-level video segmentation technique, where a video stream is divide...

Dynamic Threshold for Morphological Change Detection Algorithm

Vision-based systems for remote surveillance usually involve change detection algorithms for intruders, obstacles or irregularities detection. Real time applications require simple, fast and reliable algorithms for change detection methodology. Morphological change detection algorithm satisfies these requirements. Threshold is a very important issue for morphological change detection. Threshold...
