User choices for efficient 3D motion and shape extraction from orthographic projections

The extraction of structure-from-motion emerges in several research fields such as computer vision, video coding, biomedical engineering and human-computer interaction. The present work focuses on the algorithmic approach of structure-from-motion extraction under orthography providing, at the same time, guidelines in matters of implementation. Relative principles, constraints and stability are discussed. The improvement of the algorithm's performance w.r.t. the proposed user-choices is illustrated by means of experimental results.
