Recognition of Human Activities
نویسنده
چکیده
Motion is an important cue for the human visual system. The computer vision driven research in motion has gradually progressed over the past thirty years from the study of motion of rigid objects like boxes to more flexible objects like the human body. The developments in cameras, computers and memory have contributed in part to this maturing of computer vision. Systems that are able to detect humans and recognize their activities are part of a broad effort with applications in areas including virtual reality, smart monitoring and surveillance systems, motion analysis in sports, patient monitoring and choreography, vision-based user interfaces, etc. The understanding of human activity is a diverse and complex subject that includes tracking and modeling human activity, and representing video events at the semantic level. Its scope ranges from understanding the actions of an isolated person to understanding the actions and interactions of a crowd, or the interaction of objects like pieces of luggage or cars with persons.
