Robust Extraction of 3D Structures by Fusion of Intensity-Based and Contour-Based Junction Features.
Marielle Mokhtari, Annie Bubel, Robert Bergevin · 1998
This paper describes a new method for validating and classifying 3D junctions by combining detected intensity-based junctions and contour-based junctions. The resulting algorithm is divided in four steps: (i) the pairing of junctions according to proximity criteria, (ii) the matching of brancheslsegments of paired junctions, (iii) the validation of isolated junctions according to paired junctions and finally, (iv) the validation of brancheslsegments to complete the junction characterization. Preliminary experimental results are presented which show the effectiveness of the method to infer in a robust manner the description of 3D objects. 1.
