Although event detection in sports videos has been gaining some remarkable results, tools for exploring and exploiting these event clips on their own demands are far from user's expectation. In this paper, a novel method using spatio-temporal patterns to model visual information tailored to analyze event tactics in sports videos without tracking objects is introduced. The major contribution of the...
In this work we present a multi-modal video editing system for meetings, which uses graphical models for the segmentation and classification of the video modes. The task of video editing is about selecting the camera, that represents the meeting in the best way out of various available cameras. Therefore a new training structure for graphical models was developed. This is necessary for the learning...
We describe a navigation and coverage system based on unsupervised learning driven by visual input. Our objective is to allow a robot to remain continuously moving above a terrain of interest using visual feedback to avoid leaving this region. As a particular application domain, we are interested in doing this in open water, but the approach makes few domain-specific assumptions. Specifically, our...
The aim of this study was to elucidate the usefulness of exploratory eye movements (EEMs) in neurological and psychiatric diseases. EEMs were examined with an eye mark recorder while the subjects viewed geometric figures, visual searching tasks or video movie. Mean gazing time (MGT), total number of gazing points (TNGP) and total eye scanning length for gazing points (TESL) were analyzed. As a result,...
Advances in Internet connections speeds and computer hardware means that web content has grown richer and more interactive for users. One such area is Web3D which has seen the emergence of ISO standard technologies such as VRML (Virtual Reality Modeling Language) and its XML-based (eXtensible Markup Language) successor X3D(eXtensible 3D). X3D, in particular, presents opportunities for further integration...
Texture is an important property of fire smoke, which is a significant signal for early fire detection. This paper describes a method of analyzing the texture of fire smoke combining two innovative texture analysis tools, Wavelet Analysis and Gray Level Cooccurrence Matrices (GLCM). Tree-Structured Wavelet transform is used to represent the textural images and GLCM are used to compute the different...
