Abstract: | We propose a new method for user-independent gesture recognition from time-varying images. The method uses relative-motion
extraction and discriminant analysis for providing online learning/recognition abilities. Efficient and robust extraction
of motion information is achieved. The method is computationally inexpensive which allows real-time operation on a personal
computer. The performance of the proposed method has been tested with several data sets and good generalization abilities
have been observed: it is robust to changes in background and illumination conditions, to users’ external appearance and changes
in spatial location, and successfully copes with the non-uniformity of the performance speed of the gestures. No manual segmentation
of any kind, or use of markers, etc. is necessary. Having the above-mentioned features, the method could be successfully used
as a part of more refined human-computer interfaces.
Bisser R. Raytchev: He received his BS and MS degrees in electronics from Tokai University, Japan, in 1995 and 1997 respectively. He is currently
a doctoral student in electronics and information sciences at Tsukuba University, Japan. His research interests include biological
and computer vision, pattern recognition and neural networks.
