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
