A boundary-pair representation for perception modeling

چکیده
It is widely accepted that responses from onand o -center cells give rise to edges and are equivalent to edge detectors. In this paper, we point out that onand o -center cell responses provide more information than edges. We show that an edge-based representation makes the ownership of boundaries ambiguous and requires a combinatorial search to model perceptual grouping. By analyzing the di erences between edges and responses from onand o -center cells, we propose a boundary-pair representation, which makes the ownership of boundaries explicit and eliminates the need of a combinatorial search computationally. Each boundary in the boundary-pair representation is associated with regional attributes. We show that this representation is equivalent to a surface representation through a local di usion. This provides a uni ed representation for perception modeling. Based on this representation, a gure-ground segregation network is constructed to demonstrate the capabilities of the model in explaining many perceptual phenomena.

متن کاملSkeleton based solid representation with topology preservation
The medial axis (MA) of an object is homotopy equivalent to the solid model. This makes the medial axis a natural candidate for a skeleton representation of a general solid object. In addition, the medial axis transform (MAT) is useful for many applications in computer graphics and other areas. In many applications it is not only important to have a description of the skeleton, but also to have...
متن کاملSchwarz boundary problem on a triangle
In this paper, the Schwarz boundary value problem (BVP) for the inhomogeneous Cauchy-Riemann equation in a triangle is investigated explicitly. Firstly, by the technique of parquetingreflection and the Cauchy-Pompeiu representation formula a modified Cauchy-Schwarz representation formula is obtained. Then, the solution of the Schwarz BVP is explicitly solved. In particular, the boundary behavio...
متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
