Wavelet-based system for recognition and labeling of polyhedral junctions
Gabriel Fernandez, Terrance L. Huntsberger · Optical Engineering · 1998
. Recognition of junctions in scenes containing polyhedral objects has been shown to be an effective means of encoding for model based matching. However, noise and inconsistent lighting in the images limit the amount of useful information than can be extracted for junction identification. This paper introduces a wavelet-based system for polyhedral junction recognition that combines the waveletderived edges and line elements at multiple levels of resolution to produce a labeled image. The results of some experimental studies are also reported. Keywords and phrases. wavelets, lifting scheme, machine vision, reconstruction, key points, edges, contours, interpretation. 2. MULTIRESOLUTION EDGE DETECTOR 3 1. Introduction People might ask how it is that they can see objects in depth, meaning that human vision is "threedimensional ". The most common reply is that humans use the difference between the images in our left and right eyes to judge depth. Many techniques have been proposed to s...
