USE OF LOG POLAR SPACE FOR FOVEATION AND FEATURE RECOGNITION

The finding and maintaining of high accuracy foveation points for seve ral types of recognised feature in log polar space such as a line, cir cular or elliptical are is considered. Log polar space is preferred ov er cartesian space as it provides a high resolution and a wide viewing angle; feature invariance in the fovea simplifies foveation; it allow s multi-resolution analysis; and rotation and scale are linear transla tions in log polar space.
