This paper presents a computer-based system for assessment and training of ballet dance in a CAVE virtual reality environment. The system utilizes Kinect sensor to capture student's dance and extracts features from skeleton joints. This system depends on a structured posture space, which comprises a set of dance elements that represent key moments -- "postures", that typically will be so...
A non-contact vision-based system is presented for continuous respiratory rate monitoring. The system identifies feature points in a video feed and tracks them over time. Two methods are presented for comparison — a method which uses principal component analysis (PCA) and a simple averaging approach. These methods condense the feature point trajectories into a compact set of representative signals...
It is important to identify node role and track node evolution in temporal networks in many applications. Most existing methods identify the role of a node according to its static structural property. In this paper, we propose a new representation named quantitative temporal directed graph to represent temporal networks, which differs from other network representations in that it adds quantitative...
We propose a method for improving the accuracy of the optic cup detected from the ARGALI system. This method makes use of key points from the branching points of large vessels, the analysis of intensity variation and kinks from small vessels to obtain an enhanced optic cup. Measures used to assess the detection of the optic cup showed an 11% and 40% improvement in the mean average overlap and relative...
This paper describes a radio scanning strategy to collect the maximal number of interesting contents from multiple radio channels. Results show that knowledge about the broadcast behavior is useful to improve the collecting efficiency of the proposed approach.
We present the GT-IIR language recognition system submitted to the 2005 NIST Language Recognition Evaluation. Different from conventional frame-based feature extraction, our system adopts a collection of broad output scores from different language recognition systems to form utterance-level score distribution feature vectors over all competing languages, and build vector-based spoken language recognizers...
