Log-polar Mapping in Generalized Least-squares Motion Estimation

R. Montoliu, V.J. Traver, and F. Pla (Spain)


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.
