Abstract:
1. Method for using a computer system to automatically select key postures from a sequence of continuous image frames and abstract said key postures, said image frames depicting a human whose behavior is to be analyzed, comprising the steps of: said computer system abstracting from a series of continuous digitized images spatial features of objects contained in said images; said computer system abstracting shape features of said objects using probability calculation; said computer system detecting key posture information contained in said series of continuous images using entropy calculation; said computer system removing redundant key postures from said detected key posture information in order to obtain selected key postures; said computer system mating said selected key postures with key posture templates stored in a codebook to obtain mated postures; said computer system encoding said mated key postures to obtain series key posture codes; and said computer system comparing said series key posture codes with series codes representing human behaviors to provide an indication of what human behavior the sequence of continuous image frames depicts.
