Image projections provide an effective way of describing image contents or estimate particular kinds of motion. However, most (if not all) of previous literature on projections has been done on Cartesian images. In contrast, the work described in this paper is aimed at exploring how projections can be defined on log-polar images and how they perform in estimating motion. In the proposed algorithm,...<br/><br/>V J Traver, F Pla (2008) <i>Journal of Mathematical imaging and vision</i> 30: 2 147-165<br/>

The best parameters defining the geometry of a visual sensor generally depend on the particular visual task the sensor is intended to be used in. However, translating task requirements directly into low-level geometric parameters may be difficult, since deep knowledge of the sensor design is usually required, but end users of a sensor need not necessarily be its designers. A framework is suggested...<br/><br/>V. J. Traver, F. Pla (2008) <i>Image and Vision Computing</i> 26: 10 1354-1370<br/>

To cope with the huge amount of visual data in the environment, foveal sensing is not only an elegant biological solution, but also an appropriate mechanism in computer-based vision of artificial agents such as robots. An extremely important visual behavior in active vision systems is that of actively tracking moving targets, which is a problem closely related with foveal vision. The work describe...<br/><br/>V J Traver, F Pla (2005) <i>Computer Vision and Image Understanding</i> 97: 2 209-241<br/>

Log-polar images have been being used for pattern recognition and active vision tasks for some years. These images are obtained either from true retina-like sensors or from conventional cartesian images by software conversion. From the hardware perspective, the design of such log-polar retinae faces its own technological limitations. In the case of software remappers, however, their very flexibili...<br/><br/>V J Traver, F Pla (2003) <i></i><br/>

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-pol...<br/><br/> V. J. Traver, F. Pla (2003) <i>Image and Vision Computing </i> 21: 2 145-160<br/>

A motion estimation algorithm for log-polar images, based on the general framework of Hager and Belhumeur (1998), is presented. The advantages and disadvantages brought by the use of this kind of foveal imaging are discussed. Within this context, a simple, but quite effective approach for figure-ground segmentation is also proposed. Performance results concerning motion estimation and target segme...<br/><br/>V J Traver and F Pla (2002) <i>16 th International Conference on Pattern Recognition (ICPR)</i> 166 - 169<br/>
