Probabilistic models have been previously shown to be efficient and effective for modeling and recognition of human motion. In particular we focus on methods which represent the human motion model as a triangulated graph. Previous approaches learned models based just on positions and velocities of the body parts while ignoring their appearance. Moreover, a(More)
Consider a number of moving points, where each point is attached to a joint of the human body and projected onto an image plane. Johannson showed that humans can effortlessly detect and recognize the presence of other humans from such displays. This is true even when some of the body points are missing (e.g. because of occlusion) and unrelated clutter(More)
Context. The current generation of X-ray observatories like Chandra allows studies with very fine spatial details. It is now possible to resolve X–ray point sources projected into the cluster diffuse emission and exclude them from the analysis to estimate the " correct " X–ray observables. Aims. We wish to verify the incidence of point sources on the(More)
Aims. In this paper we re-visit the observational relation between X–ray luminosity and temperature for high-z galaxy clusters and compare it with the local L X –T and with theoretical models. Methods. To these ends we use a sample of 17 clusters extracted from the Chandra archive supplemented with additional clusters from the literature, either observed by(More)
Context. With the superb angular resolution of the Chandra Observatory, it is now possible to detect X–ray point sources, either embedded in galaxy clusters or along the cluster line of sight, which could not be resolved by previous instruments. This now allows studies of source counts in distant cluster fields. Aims. We want to analyze the inner region of(More)
