Image classifying method for recognizing face, involves calculating distance between image of category of objects and sub-assembly according to specific formula, and comparing calculated distance with decision threshold

摘要

#CMT# #/CMT# The method involves obtaining a sub-assembly of images of a category of objects, where the sub-assembly is associated to a classification characteristic. The distance between an image of the category of objects and the sub-assembly is calculated according to a specific formula having parameters such as distance between an image vector corresponding to the image and vectors of images. The calculated distance is compared with a decision threshold. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device comprising a unit for classifying an image of an object belonging to a category of objects (2) a computer program comprising a set of instructions for performing a image classifying method. #CMT#USE : #/CMT# Method for classifying an image of an object belonging to a category of objects using computer for recognizing a face (claimed). Can also be used for classifying objects according to various classification characteristics and for classifying images of logos. #CMT#ADVANTAGE : #/CMT# The method quickly classifies the images such as still images, independent of the effectiveness of a system used in upstream for detection of blockage elements. The method is robust with respect to large variations in the images between them. The method classifies different types of faces in frontal, semi-fontal and outline exposures for facial recognition in a robust manner with respect to luminous variations and to the presence of the elements during an acquisition phase and an identification phase. The method obtains the coherent classification with respect to acquisition images, distributed in the sub-assembly of positive images, corresponding to the classification characteristic, and obtains a set of negative images such as non frontal exposures. The method improves the ratio of classification of the images in an effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart of stages of a utilization phase of an image classifying method.
