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, each attached to a joint of the human body and projected onto an image. 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 parts are missing (e.g., because of occlusion) and unrelated clutter points are added to the(More)

Extended radio emission detected around a sample of GHz Peaked Spectrum (GPS) radio sources is discussed. Evidence of related extended emission is found in 6 objects out of 33. Three objects are associated with quasars with corejet pc-scale morphology, and three more are identified with galaxies with symmetric (CSO) morphology. We conclude that for the(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 cluster(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 LX–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)
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)
We define a complete sample of thirty-three GHz-Peaked-Spectrum (GPS) radio sources based on their spectral properties. We present measurements of the radio spectra and polarization of the complete sample and a list of additional GPS sources which fail one or more criteria to be included in the complete sample. The majority of the data have been obtained(More)
We present results from global VLBI (Very Long Baseline Interferometry) observations at 5 GHz of the radio source OQ208. The milliarcsecond (mas) morphology of the radio emission is described by an asymmetric compact double structure with a flux density ratio between the two components of about 10:1, and a projected total size of ∼ 7 mas (i.e. ∼ 7 pc). Both(More)
Vision is a primary sense that allows human beings to interact with their environment and motion is one of the most important cues that vision can explore and utilize. In this thesis, we present computational approaches to the problems of inferring three-dimensional motion information and perceiving two-dimensional human motions from a sequence of images(More)
