Hierarchical Keyframe-based Video Summarization Using QR-Decomposition and Modified k-Means Clustering
We propose a novel hierarchical keyframe-based video summarization system using QR-decomposition. Specially, we attend to the challenges of defining some measures to detect the dynamicity of a shot and video and extracting appropriate keyframes that assure the purity of video summary. We derive some efficient measures to compute the dynamicity of video shots using QRdecomposition, and we utiliz...
متن کاملContent-Based Keyframe Clustering Using Near Duplicate Keyframe Identification
In this paper, the authors propose an effective content-based clustering method for keyframes of news video stories using the Near Duplicate Keyframe (NDK) identification concept. Initially, the authors investigate the near-duplicate relationship, as a content-based visual similarity across keyframes, through the Near-Duplicate Keyframe (NDK) identification algorithm presented. The authors assi...
متن کاملExtraction based approach for text summarization using k-means clustering
This paper describes an algorithm that incorporates kmeans clustering, term-frequency inverse-document-frequency and tokenization to perform extraction based text summarization.
متن کاملVideo Summarization Using Singular Value Decomposition
In this paper, we propose a novel technique for video summarization based on the Singular Value Decomposition (SVD). For the input video sequence, we create a feature-frame matrix A, and perform the SVD on it. From this SVD, we are able to not only derive the reened feature space to better cluster visually similar frames, but also deene a metric to measure the amount of visual content contained...
متن کاملVSCAN: An Enhanced Video Summarization Using Density-Based Spatial Clustering
In this paper, we present VSCAN, a novel approach for generating static video summaries. This approach is based on a modified DBSCAN clustering algorithm to summarize the video content utilizing both color and texture features of the video frames. The paper also introduces an enhanced evaluation method that depends on color and texture features. Video Summaries generated by VSCAN are compared w...
