摘要
The invention relates to a method for recognising faces in digital images consisting in providing for a knowledge base which contains face images and is hierarchical into several classes each of which comprises different images of the same person. Said invention relates to pre-processing said knowledge base in such a way that a minimisation of variance in each class and a maximisation of variance between different classes are simultaneously obtainable, thereby making it possible to form a vectorial base comprising the discriminant components of said knowledge base. The comparison of a recognisable face with a pre-processed reference face such as the knowledge base and an eventual reconstruction of a recognised face are also disclosed.
