Motion estimation, Generalized least-squares, Log-polar mapping.
This work presents a study of how log-polar images can
be combined with a generalized least squares-based technique in order to get an accurate and fast parametric motion estimation algorithm. The possibility of replacing
the classical hierarchical algorithm —based on using a
pyramid of multiple resolution— by an algorithm which
gets a good aproximation of the motion parameters using
log-polar images, is also explored.
