In this paper. we propose a method for detecting a human being using silhouette projection pattern matching, and present experimental results of its application in video surveillance systems. There are some studies on detecting intruders in video images by exuacting changing regions which follow moving targets. However, detection e m caused by small animals, changes in brightness due to sunshin...

Individuals with glucocorticoid-induced osteoporosis experience vertebral fractures at an increased rate and at higher vertebral areal bone mineral density (aBMD) than individuals with primary osteoporosis. Standard posteroanterior- (PA-) projection dual energy X-ray absorptiometry (DXA) lacks the diagnostic sensitivity required for reliable estimation of vertebral fracture risk in individuals....

We discuss how well a given convex body B in a real d-dimensional vector space V can be approximated by a set X for which the membership question: “given an x ∈ V , does x belong to X?” can be answered efficiently (in time polynomial in d). We discuss approximations of a convex body by an ellipsoid, by an algebraic hypersurface, by a projection of a polytope with a controlled number of facets, ...

The paper presents the results of research on the development of a framework and new tools for perceptually oriented visualization of human motion, in particular, a gait. Presented in this paper are new tools for visualizing motion and gait of a human. Their implementation is based on the following principles: i) translational motion component is omitted and time-varying orientations of individ...

The goal of the present study was to examine the contribution of thalamo-amygdala and thalamo-cortico-amygdala projections to fear conditioning. Lesions were used to destroy either the thalamo-cortico-amygdala projection, the thalamo-amygdala projection, or both projections, and the effects of such lesions on the acquisition of conditioned fear responses (changes in arterial pressure and freezi...

OBJECTIVE The literature highlights two possible roles for the mother-daughter relationship in the development of weight concern in young girls. The first is simply as a forum for modeling the mother's own concerns and the second is as an interaction between two individuals, which is either protective or facilitative of weight concern. The present study aimed to assess both the modeling and the...

role in processing of sensory stimuli during emotional situations. These nuclei, which include the suprageniculate nucleus (SG), the posterior intralaminar nucleus (PIN), the peripeduncular nucleus (PP) and the medial division of the medial geniculate body (MGm), project to both cortex and amygdala, but target areas and the extent of the projection of individual nuclei are not known yet. The ai...

We introduce and study a sequence of geometric invariants for convex bodies in finite-dimensional spaces, which is in a sense dual to the sequence of mean Minkowski measures of symmetry proposed by the second author. It turns out that the sequence introduced in this paper shares many nice properties with the sequence of mean Minkowski measures, such as the sub-arithmeticity and the upper-additi...

We give a different proof of a recent result of Klartag [12] concerning the concentration of the volume of a convex body within a thin Euclidean shell and proving a conjecture of Anttila, Ball and Perissinaki [1]. It is based on the study of the Lp-centroid bodies. We prove an almost isometric reverse Hölder inequality for their mean width and a refined form of a stability result.

We disprove a conjecture of A. Koldobsky asking whether it is enough to compare (n−2)-derivatives of the projection functions of two symmetric convex bodies in the Shephard problem in order to get a positive answer in all dimensions.
