Defect Inspection System for Shape-based Matching Using Two Cameras
This research is regarding the application of a vision algorithm to investigates various approaches for automated inspection in of gluing process using shape-based matching application in order to control the decision making concerning jobs and work pieces recognition that are to be made during system operation in real time. A new supervised defect detection approach to detect a class of defect...
متن کاملViewpoint independent matching of planar curves in 3D space
We present a new approach to match planar curves using the weak perspective projection model. This is based on a set of shape parameters that can be extracted from a closed or open contour, derived from the original image as a (s) boundary code. In order to reduce the complexity and increase the robustness of the matching process, the original parameters are reduced to a set of three intermedia...
متن کاملModeling Planar Shape Variation via Hamiltonian Flows of Curves
The application of the theory of deformable templates to the study of the action of a group of diffeomorphisms on deformable objects provides a powerful framework to compute dense one-to-one matchings on d-dimensional domains. In this paper, we derive the geodesic equations that govern the time evolution of an optimal matching in the case of the action on 2D curves with various driving matching...
متن کاملPlanar shape representation and matching under projective transformation

This paper introduces a new representation for planar objects which is invariant to projective transformation. Proposed representation relies on a new shape basis which we refer to as the conic basis. The conic basis ta...
متن کاملPerforming boundary shape matching in spatial data
Edwin M. Knorr, Raymond T. Ng, David L. Shilvock Department of Computer Science University of British Columbia Vancouver, B.C., V6T 1Z4, Canada fknorr,[email protected] Abstract This paper describes a new approach to knowledge discovery among spatial objects|namely that of partial boundary shape matching. Our focus is on mining spatial data, whereby many objects called features (represented as pol...
