Viene definito un funzionale che dipende dalla simmetria delle variazioni del gradiente, data la metà verticale della faccia. Il metodo si basa sulla valutazione del funzionale, che appunto evidenzia le variazioni simmetriche del profilo di luminanza. Potrebbe essere interessante per la ricerca degli occhi o delle sopracciglia, in quanto le proprietà che si ricercano devono essere il più possibile simmetriche.

X Abstract

Locating facial features is crucial for various face recognition schemes. The authors suggest a robust facial feature detector based on a generalized symmetry interest operator. No special tuning is required if the face occupies 15-60% of the image. The operator was tested on a large face data base with a success rate of over 95%

CiteULike organises scholarly (or academic) papers or literature and provides bibliographic (which means it makes bibliographies) for universities and higher education establishments. It helps undergraduates and postgraduates. People studying for PhDs or in postdoctoral (postdoc) positions. The service is similar in scope to EndNote or RefWorks or any other reference manager like BibTeX, but it is a social bookmarking service for scientists and humanities researchers.
