Weighted multi-view key-frame extraction
The extraction of representative key-frames from video shots is very important in video processing and analysis, since it constitutes the basis for several important tasks such as video shot summarization, browsing and retrieval as well as high-level video segmentation. The extracted key-frames should capture a great percentage of the information of a shot content, while at the same time they s...
متن کاملKey Frame Extraction from Motion Capture Data by Curve Saliency
We propose a new method for extracting key frames from a motion capture sequence. Our proposed approach consists of two steps. In the first step, we propose a new metric, curve saliency, for motion curves that specifies the important frames of the motion. In the second step, we detect the final key frames by clustering the computed important frames. As a result of our experimental results, on t...
متن کاملA novel video key-frame-extraction algorithm based on perceived motion energy model
The key frame is a simple yet effective form of summarizing a long video sequence. The number of key frames used to abstract a shot should be compliant to visual content complexity within the shot and the placement of key frames should represent most salient visual content. Motion is the more salient feature in presenting actions or events in video and, thus, should be the feature to determine ...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
15 صفحه اولEfficient Key-Frame Extraction and Video Analysis
Content based video indexing and retrieval has its foundations in the analyses of the prime video temporal structures. Consequently, technologies for video segmentation and key-frame extraction have become crucial for the development of advanced digital video systems. Conventional algorithms for video partitioning and keyframe extraction are mainly implemented autonomously. By focusing the anal...
