A New Local Descriptor Based on Strings for Face Recognition by Hicham Zaaraoui, Abderrahim Saaidi, Rachid El Alami, Mustapha Abarkan

“…This paper proposes the use of strings as a new local descriptor for face recognition. The face image is first divided into nonoverlapping subregions from which the strings (words) are extracted using the principle of chain code algorithm and assigned into the nearest words in a dictionary of visual words (DoVW) with the Levenshtein distance (LD) by applying the bag of visual words (BoVW) paradigm. …”
