Abstract
Object recognition is an automated image processing application of great interest in areas ranging from defect inspection to robot vision. In this regard, the generalized Hough transform (GHT) is a well-established technique for the recognition of geometrical features out of binary images even corrupted by noise or when the target is partially occluded. In order to enhance the performance of the original algorithm in detecting a given geometrical feature out of a single image, we consider the transformation of an stereo pair of a 3D scene under the GHT, one of the images using the template we are looking for and the other using its corresponding according to the perspective transformation that relates the images of the stereo pair. Validation experiments using partially occluded targets in noisy environments are presented.
