Shot change detection is a main technique for automatic temporal segmentation of video, which requires adaptive adjustment of thresholds. In this paper, we propose an adaptive shot change detection algorithm using histograms of frames within extension sliding window. The proposed method generates an adaptive threshold which is calculated by an average of absolute difference histogram within extension...
In this paper, we propose a fast partial distortion algorithm using normalized dithering matching scan to get uniform distribution of partial distortion which can reduce only unnecessary computation significantly. Our algorithm is based on normalized dithering order matching scan and calibration of threshold error using LOG value for each sub-block continuously for efficient elimination of unlike...
Shot change detection is a main technique for automatic temporal segmentation of video, which requires adaptive adjustment of thresholds and real-time operation in actual applications. To date, few researches have been conducted on real-time shot change detection to be applied to hardware terminals with low performance such as PMPs (portable media player) and cellular phones. In this paper, we propose...
The video segmentation is a main technique for automatic management of video data. We propose the video segmentation algorithm using thresholds and weighting based on moving sliding window. The proposed method generates threshold and weighting factor using feature value of frame on moving sliding window. And we improve our algorithms to apply adaptive for various video data. We apply variable weighting...
Shot change detection is the main technique for automatic temporal segmentation of video. Until now, there were little research reports about real-time shot change detection for applying to hardware terminals with low performance such as PMPs (Portable Multimedia Player) and cellular phones. In this paper, we propose an adaptive real-time shot change detection algorithm using sub-sampling, weighting...
