Use of log polar space for foveation and feature recognition
Fee-Lee Lim, GEOFF A. W. WEST, Svetha Venkatesh · IEE Proceedings - Vision Image and Signal Processing · 1997
The finding and maintaining of high accuracy foveation points for several types of recognised feature in log polar space such as a line, circular or elliptical arc is considered. Log polar space is preferred over cartesian space as it provides a high resolution and a wide viewing angle; feature invariance in the fovea simplifies foveation; it allows multi-resolution analysis; and rotation and scale are linear translations in log polar space.
