It is known that a tree convex network is globally consistent if it is path consistent. However, if a tree convex network is not path consistent, enforcing path consistency on it may not make it globally consistent. In this paper, we investigate the properties of some tree convex constraints under intersection and composition. As a result, we identify a sub-class of tree convex networks that ar...

Research on the interpretation of image flow (or optical flow) until now has mainly focused on instantaneous flow fields. This limits the scope of the problems that one can address and the accuracy of the results. Here we extend a previous formulation of the problem to incorporate temporal variation of image flow. We illustrate our approach by solving specific cases which are of practical signi...

This paper presents a practical system for vision-based traffic scene analysis from a moving vehicle based on a cognitive feedback loop which integrates real-time geometry estimation with appearance-based object detection. We demonstrate how those two components can benefit from each other’s continuous input and how the transferred knowledge can be used to improve scene analysis. Thus, scene in...

Instead of the old myths of death and resurrection, of victory and twilight of the gods, which the Enlightenment removed from people’s consciousness, the nineteenth century has justified the barren idea that life moves like some sort of transportation on a straight road, and that one can increase speed or change direction. However, life never advances one-dimensionally, neither forwards nor bac...

One of the desiccation-tolerant mechanisms of the resurrection plant, Xerophyta humilis, is the ability to shut down photosynthesis reversibly. The X. humilis psbR and ChlP genes, encoding the 10 kDa polypeptide of photosystem II (PSII) and a geranylgeranyl reductase, respectively, were isolated in a differential display screen as dehydration-down-regulated and rehydration-up-regulated transcri...

The article is about the critical analysis of modern understanding “death personality”. point view early Christian teacher Eastern Church Athenagoras Athens taken as basis this consideration. His heritage “On Resurrection Dead” tells us that man an immortal being. author introduces a certain terminology to describe process immortality human nature. According Athenagoras, death ordinary process,...
