User Choices for E cient D Motion and Shape Extraction from Orthographic Projections

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 orthogra phy 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 The improvement of the algorithm s performance w r t the proposed user choices is illus trated by means of experimental results
