Blocks World Revisited: Image Understanding Using Qualitative Geometry and Mechanics
Since most current scene understanding approaches operate either on the 2D image or using a surface-based representation, they do not allow reasoning about the physical constraints within the 3D scene. Inspired by the “Blocks World” work in the 1960’s, we present a qualitative physical representation of an outdoor scene where objects have volume and mass, and relationships describe 3D structure...
متن کاملSliding Blocks Revisited: a Simulational Study
Received (received date) Revised (revised date) A computational study of sliding blocks on inclined surfaces is presented. Assuming that the friction coefficient µ is a function of position, the probability P (λ) for the block to slide down over a length λ is numerically calculated. Our results are consistent with recent experimental data suggesting a power-law distribution of events over a wid...
متن کاملBlocks World Tamed Ten Thousand Blocks in under a Second
Blocks World (BW) has been a standard example of a planning domain for almost thirty years, and it is still commonly used to illustrate the capabilities both of formalisms and of planners. As a minimum, therefore, we should know certain basic things about the domain. It is clear that BW planning, in the sense of nding some plan or other, is trivial, and it was shown in 1991 that nding optimal (...
متن کاملThe world of krypton revisited.
Element 36 takes its name from the Greek word, kryptos meaning hidden. Like all other members of group 18 (the noble gases), it is colourless, odourless, and occurs in only minute amounts in the Earth’s atmosphere (1.14 ppm in dry air). It was Sir William Ramsay who, following the 1894 discovery of argon with Lord Rayleigh, suggested that a new family of elements would now need to be accommodat...
متن کاملSmall-World Brain Networks Revisited
It is nearly 20 years since the concept of a small-world network was first quantitatively defined, by a combination of high clustering and short path length; and about 10 years since this metric of complex network topology began to be widely applied to analysis of neuroimaging and other neuroscience data as part of the rapid growth of the new field of connectomics. Here, we review briefly the f...
