Among the different aspects of converting an engineering drawing to CAD, 3-D reconstruction from several views has only been dealt with from a geometric perspective, although a lot of information is of symbolic nature and can be recognized as such directly on a single view. In this paper, we present a first prototype of a system combining geometric reconstruction through the “fleshing out proje...

We present an approach for learning a mapping between geometric states and logical predicates. This mapping is a necessary part of any robotic system that requires task-level reasoning and path planning. Consider a robot tasked with putting a number of cups on a tray. To achieve the goal the robot needs to find positions for all the objects, and if necessary may need to stack one cup inside ano...

with at least 11 hectares site locating on fashafooyeh from rey town, the archaic area of nachir khanloq is one of the important regions from islamic period that has been less noticed yet. unfortunately, some parts of this region have been leveled by farming equipments. in addition to its large area, great and massive distribution of cultural artifacts throughout this area, particularly several...

We approach the integration between symbolic and subsymbolic processing within a hybrid model of visual perception, intended for an autonomous intelligent system. No hypotheses are made about the adequacy of this model as a model of human vision: the proposed model is currently under development for a robot system. We propose an associative mapping mechanism, that relates the constructs of the ...

A systematic framework is presented for solving algebraic equations arising in geometric constraint solving. The framework has been used successfully to solve a family of spatial geometric constraint problems. The approach combines geometric reasoning, symbolic reduction, and homotopy continuation.

for some 3 million years, the archaeological record is characterized by stone tools undergoing incremental changes. then around 40,000 years ago, the monotony of lithics is terminated by a profusion of visual representations, generally considered to be the world’s first objets d’art. this collection include a series of portable objects, especially figurines and, later on, the famous cave painti...
