Video Classification and Shot Detection for Video Retrieval Applications
Appropriate organization of video databases is essential for pertinent indexing and retrieval of visual information. This paper proposes a new feature called Block Intensity Comparison Code (BICC) for video classification and an unsupervised shot change detection algorithm to detect the shot changes in a video stream using autoassociative neural network (AANN) which makes retrieval problems muc...
متن کاملActivity Based Video Content Trajectory Representation and Segmentation
A novel approach is developed to segment continuous CCTV recordings according to the activities captured in the scene. This approach differs from previous approaches which are mostly based on shot change detection and shot grouping. Video content is represented by constructing a cumulative multi-event histogram over time. An on-line segmentation algorithm is then proposed to detect breakpoints ...
متن کاملAutomatic Shot Change Detection Algorithm Using Multi-stage Clustering for MPEG-Compressed Videos
Automatic shot change detection has been recognized as an important research issue for video classification. This paper proposes an automatic clustering-based algorithm for shot change detection in MPEG-compressed videos with a small number of user-defined parameters. For accurate detection of abrupt and gradual shot changes, the proper selection and extraction of features are important. We fir...
متن کاملAn unified framework for shot boundary detection via active learning
Video shot boundary detection is an important step in many video processing applications. We observe that video shot boundary is a multi-resolution edge phenomenon in the feature space. In this paper, we expanded our previous temporal multi-resolution analysis (TMRA) work by introducing the new feature vector based on motion. Further we employ the support vector machine (SVM) to refine the clas...
متن کاملIntroduction to Computational and March 2 Nd 2006 Biological Vision
What is a "SHOT"? What we are looking for Shot – an abrupt change in the scene i.e. change of scene, change of camera angle (change of active camera). Shot detection in video is also called – video segmentation. If we compare stills image segmentation to video segmentation, then the homogeneous regions in image are homogeneous sequences in video and boundaries in images are actually the shots i...
