....sequences for a total of approximately 10 frames. The algorithm is demonstrated to be accurate and efficient. 1 Introduction Humans have developed a remarkable ability in perceiving the posture and motion of the human body ( biological motion in the human vision literature) Johansson [7] filmed people acting in total darkness with small light bulbs fixed to the main joints of their body. A single frame of a Johansson movie is nothing but a cloud of bright dots on a dark field# however,assoonasthemovie is animated one can readily detect, count, segmentanumber of people in a scene, ....

....and biking in the same direction. We used point features (from a corner detector) in our experiments because they are easier to obtain compared to body segments that may be hard to detect in case of severe occlusion. Another reason is that psychophysics experiments (Johansson s experiments [19]) show that the human visual system can perceive vivid human motion from moving dots representing the motion of the main joints of the human body. But, the algorithms can also be applied to other types of features. A systematic study of the trade off between model complexity (number of components ....

Similarly, pathologies of the heart can be characterized by the patterns of sistolic and diastolic phases# dance steps, hand gestures and facial expressions can be characterized by the dynamics of movement of body parts [ Johansson, 1973 ] # economic states such as recession can be characterized by the dynamics of economic indicators# syntactic categories can be categorized by the dynamics of word transitions [ Charniak, 1993 ] # and so on. The goal of this work is to enable mobile robots to learn the dynamics of their ....

....to perceive certain invariances or affordances within the visual scene directly, without much processing or interpretation at all. Thus the motion of dots fixed to the joints of a dancer is readily seen as human, because they preserve some invariant relationships about limb lengths and motions [9]. The Helmholtzian view is that perception is an exploratory process in which visual sensory information is evaluated against the viewer s expectations about the scene; a topdown, rather than a bottom up process. Hochberg s paper had two main aims: a theoretical one, to contrast Helmholtzian and ....

The Specialized Mappings Architecture - Rosales, Sclaroff (2003) (Correct)
....humans can easily estimate the articulated pose and motion of people in a scene, given only relatively low resolution, monocular images of the world, e.g. from a photograph or a video. It is believed that humans employ extensive prior knowledge about human body structure and motion in this task [22]. Assuming this, in this paper we will consider how a computer might learn the underlying knowledge in the form of a probabilistic model, and thereby infer pose from a single image. Let us consider an example pose inference task: given only a person s silhouette, estimate that person s ....

A striking demonstration of the capabilities of the human visual system is provided by the experiments of Johansson [13].
