Spatio-temporal Feature Classifier
Different from current foreground and background segmentation methods, we did not utilize the low level image representation method (such as boundaries and textures) to extract the feature of the videos, instead we proposed a spatio-temporal feature classifier to obtain the union region of object from natural videos as the interest points. We slide the temporal chunk along time axis to obtain s...
متن کاملRobust Spatio-temporal Feature Tracking
Simultaneous tracking of features acquired by multiple video cameras mounted on a rig opens new possibilities for ego-motion estimation and 3D scene modeling. In this paper we propose a novel approach of tracking three video streams at once. The color image features are detected using interest operators and described with SIFT. Since standard tracking techniques perform outlier detection only a...
متن کاملSpatio-Temporal Self-Organizing Feature Maps
Thus far, the success of capturing and classifying temporal information with neural networks has been limited. Our methodology adds a spatio-temporal coupling to the Self-Organized Feature Map (SOFM) which creates temporally and spatially localized neighborhoods in the map. The spatio-temporal coupling is based on traveling waves of activity starting at each winning node which are naturally att...
متن کاملSpatio-temporal analysis of feature-based attention.
The cortical mechanisms of feature-selective attention to color and motion cues were studied in humans using combined electrophysiological, magnetoencephalographic, and hemodynamic (functional magnetic resonance imaging) measures of brain activity. Subjects viewed a display of random dots that periodically either changed color or moved coherently. When attention was directed to the color change...
متن کاملSpatio-temporal Feature Recogntion using Randomised Ferns
In this paper we present a generic classifier for detecting spatio-temporal feature points within video. The premise being that given a feature detector, we can learn a classifier that duplicates its functionality which is both accurate and computationally efficient. This means that feature point detection can be achieved independent of the complexity of the original interest point formulation....
