— Most conventional methods of feature extraction do not pay much attention to the geometric properties of data, even in cases where the data have spatial features. In this study we introduce geometric algebra to undertake various kinds of feature extraction from spatial data. Geometric algebra is a generalization of complex numbers and of quaternions, and(More)
Human Activity Recognition is one of the most important areas of computer vision research. Its applications include intelligent security monitoring systems, health care systems, intelligent transportation systems, and a variety of systems that involve interactions between people and electronic devices such as human computer interfaces. However, the biggest(More)
