Challenges in Learning the Appearance of Faces for Automated Image Analysis - Part 2

Published on Feb 25, 20073627 Views

Thomas Vetter

The variability of images of the human face challenges research in machine vision since its beginning. Sources of variability not only include individual appearance but also cover external parameters

Workshop on Pattern Recognition and ML 2004 - Grenoble
