Distributed mission critical systems require support for ultra-secure communication, in which intrusions must be detected and suppressed in real time, possibly before the aaected messages reach the receiver. When the distributed application has real-time requirements , the eeects of intrusion are particularly severe. In addition to covered channels and potentially tampered data at the receiver,...

Finally, there is a definition problem between monophonic and polyphonic sounds. In the case of monophonic sound, the obvious definition is to pick the lowest partial as the fundamental frequency. In the case of polyphonic sounds, resulting either from one source (e.g., a piano) or from many sources (e.g., orchestra, choir), the definition is far more difficult, and approaches close to the prob...

Motivation: Most object detection tasks in computer vision are computationally extensive because of a) the large amount of input data that has to be processed and b) the use of complex classifiers that are robust against pose and illumination changes. Speeding-up the classification is therefore of major concern when developing systems for real-world applications. We investigate two methods for ...

This paper describes a syntactic approach to the classiication of moving objects in front of a video camera. The implementation of syntactic pattern recognition techniques is examined for a real-time system, focusing on the detection of human heads in front of a video camera. In particular, I will be describing the technique used to classify objects between heads and non-heads, the results achi...
