User Choices for Efficient 3D Motion and Shape Extraction from Orthographic Projections

Abstract

The problem of estimating three dimensional motion and structure of objects from monoc-ular image sequences has drawn particular attention since the past decade. The extraction of structure-from-motion emerges in research elds such us computer vision, video coding, biomedical engineering and human-computer interaction. Present work focuses on the algorithmic approach of structure-from-motion under orthography providing, at the same time, guidelines in matters of implementation. Relative principles, constraints and stability matters are discussed. Asymptotic behaviour and consistency of the proposed estimators is analyzed in [12]. The improvement of the algorithm's performance w.r.t. the proposed user-choices is illustrated by means of experimental results
