We present an object recognition system based on symbolic graphs with object corners as vertices and outlines as edges. Corners are determined in a robust way by a multiscale combi...
This paper presents an efficient extraction method of closed loops as primitive symbols of line drawings, and an robust line drawing understanding system incorporating this extrac...
We describe an approach to the computation of symbolic resultants in which factors are removed during the course of the calculation, so reducing the stack size required for interme...
Convexity is an important property in nonlinear optimization since it allows to apply efficient local methods for finding global solutions. We propose to apply symbolic methods t...
In this paper, we present a novel unifying concept of pairwise spatial relations. We develop two way directional relations with respect to a unique point set, based on topology of ...
