Feature Extraction and Registration – An Overview
Stefan Seeger · 2002
The purpose of this paper is to present a survey of rigid registration (also called matching) methods applicable to surface descriptions. As features are often used for the registration task, standard feature extraction approaches are described in addition. In order to give the reader a framework for his present registration problem, this report divides the matching task into three major parts (feature extraction, similarity metrics and search strategies). In each of them the reader has to decide between several possibilities, whose relations are in particularly pointed out. 1
