Translation Estimation in Log-Polar Images
نویسندگان
چکیده
Log-polar mapping plays a fundamental role in active vision by allowing both a wide eld-of-view and a high-accuity area. While log-polar mapping simpli es certain visual tasks, translation estimation becomes more diÆcult in this domain. However, given the importance of translational motion for mobile target tracking, solving this problem in log-polar space is of great signi cance. In this paper, we present some preliminary results of translational motion estimation using log-polar images.

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. Experimenta...
متن کاملDealing with 2D translation estimation in log-polar imagery
Log-polar mapping has been proposed as a very appropriate space-variant imaging model in active vision applications. This biologically inspired model has several advantages, and facilitates some visual tasks. For example, it provides an efficient data reduction, and simplifies rotational and scaling image transformations. However, simple translations become a difficult transform due to the log-...
متن کاملVisual Tracking using Kernel Projected Measurement and Log-Polar Transformation
Visual Servoing is generally contained of control and feature tracking. Study of previous methods shows that no attempt has been made to optimize these two parts together. In kernel based visual servoing method, the main objective is to combine and optimize these two parts together and to make an entire control loop. This main target is accomplished by using Lyapanov theory. A Lyapanov candidat...
متن کاملEgomotion Estimation Using Log-Polar Images
We address the problem of egomotion estimation of a monocular observer moving with arbitrary translation and rotation in an unknown environment, using log-polar images. The method we propose is uniquely based on the spatio-temporal image derivatives, or the normal ow. Thus, we avoid computing the complete optical ow eld, which is an ill-posed problem due to the aperture problem. We use a search...
متن کاملLog-polar Mapping in Generalized Least-Squares Motion Estimation
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 ...
