Accurate estimation of the objetct motion in image sequences

Abstract

The aim of this thesis is to contribute in the calculation of variational optical flow methods. Tis is a basic topic in the field of computer vision that pursues the accurate estimation of the displacement experienced by the objects present in a video scene. In particular, this dissertation is focused on two main themes: (i) we study the influence of temporal information compared to traditional spatial variational methods; (ii) we analyze several strategies for the preservation of flow discontinuities and propose alternatives to overcome this problem.

El objetivo de esta tesis es contribuir en el cálculo de flujo óptico. Este es un tema importante dentro del campo de la visión por computador que persigue estimar de manera precisa el desplazamiento que experimentan los objetos presentes en una escena de vídeo. Su importancia es muy elevada ya que sirve como base para un amplio número de aplicaciones dentro del campo de la visión artificial
