Joint Video Scene Segmentation and Classification based on Hidden Markov Model
نویسندگان
چکیده
Video classi cation and segmentation are fundamental steps for e cient accessing, retrieving and browsing large amount of video data. We have developed a scene classi cation scheme using a Hidden MarkovModel (HMM)based classi er. By utilizing the temporal behaviors of di erent scene classes, HMM classi er can e ectively classify video segments into one of the prede ned scene classes. In this paper, we describe two approaches for joint video classi cation and segmentation based on HMM, which works by searching for the most likely class transition path utilizing the dynamic programming technique.

متن کاملFootball Video Segmentation Based on Video Production Strategy
We present a statistical approach for parsing football video structures. Based on video production conventions, a new generic structure called ‘attack’ is identified, which is an equivalent of scene in other video domains. We define four video segments to construct it, namely play, focus, replay and break. Two middle level visual features, play field ratio and zoom size, are also computed. The ...
متن کاملSemantic Image Segmentation with a Multidimensional Hidden Markov Model
Segmenting an image into semantically meaningful parts is a fundamental and challenging task in image analysis and scene understanding problems. These systems are of key importance for the new content based applications like object-based image and video compression. Semantic segmentation can be said to emulate the cognitive task performed by the human visual system (HVS) to decide what one "see...

Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
متن کاملThe Segmentation and Classification of Story Boundaries in News Video
The segmentation and classification of news video into single-story semantic units is a challenging problem. This research proposes a two-level, multi-modal framework to tackle this problem. The video is analyzed at the shot and story unit (or scene) levels using a variety of features and techniques. At the shot level, we employ a Decision Tree to classify the shot into one of 13 pre-defined ca...
