A database model for querying visual surveillance videos by integrating semantic and low-level features
(Springer, Berlin, Heidelberg, 2005)
Automated visual surveillance has emerged as a trendy application domain in recent years. Many approaches have been developed on video processing and understanding. Content-based access to surveillance video has become a ...
Real-time fire and flame detection in video
This paper proposes a novel method to detect fire and/or flame by processing the video data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame and fire flicker is ...
Saliency for animated meshes with material properties
We propose a technique to calculate the saliency of animated meshes with material properties. The saliency computation considers multiple features of 3D meshes including their geometry, material and motion. Each feature ...
Direct volume rendering of unstructured grids
(Pergamon Press, 2003)
This paper investigates three categories of algorithms for direct volume rendering of unstructured grids, which are image-space, object-space, and hybrid methods. We propose three new algorithms. Cell Projection algorithm, ...
Three-dimensional scene representations: modeling, animation, and rendering techniques
Modeling the behavior and appearance of captured three-dimensional (3D) objects is a fundamental requirement for scene representation in a three-dimensional television (3DTV) framework. By using the data acquired from ...
Surveillance using both video and audio
It is now possible to install cameras monitoring sensitive areas but it may not be possible to assign a security guard to each camera or a set of cameras. In addition, security guards may get tired and watch the monitor ...
Modeling, animation, and rendering of human figures
Modeling and visualization of complex geometric environments
Visualization of large geometric environments has always been an exciting project for computer graphics practitioners. Modern graphics workstations allow rendering of millions of polygons per second. Although these systems ...
Early wildfire smoke detection based on motion-based geometric image transformation and deep convolutional generative adversarial networks
(Institute of Electrical and Electronics Engineers Inc., 2019)
Early detection of wildfire smoke in real-time is essentially important in forest surveillance and monitoring systems. We propose a vision-based method to detect smoke using Deep Convolutional Generative Adversarial Neural ...
An MPEG-7 compatible video retrieval system with integrated support for complex multimodal queries
(IEEE Computer Society, 2019)
We present BilVideo-7, an MPEG-7 compatible, video indexing and retrieval system that supports complex multimodal queries in a unified framework. An MPEG-7 profile is developed to represent the videos by decomposing them ...
