An Optimization Approach for Translational Motion Estimation in Log-Polar Domain

Log-polar imaging is an important topic in space-variant active vision, and facilitates some visual tasks. Translation estimation, though essential for active tracking, is more difficult in (log-)polar coordinates. We propose here a novel, conceptually simple, effective, and efficient method for translational motion estimation. It is based on a gradient-based minimization procedure. Experimental results with log-polar images using a software-based log-polar remmapper are presented.
