A new Log-Polar Mapping for Space Variant Imaging : Application to Face Detection and Tracking
International audience Space-variant images (images whose resolution changes across the image) supply a powerful image representation for active vision systems. In this article a new log-polar mapping is presented. The main originality of this mapping is its great flexibility. Unlike other approache...
