Method of object recognition, apparatus of the same and recording medium therefor

An object recognition apparatus comprising at least learning means for learning a first entered image, and recognition means for recognizing a second entered image, wherein said learning means includes:

• means for entering the first image including the object to be learned,
• means for dividing said entered image into a first partial image,
• means for classifying said first partial image into plural classes,
• means for calculating a matrix for feature extraction from said partial images image classified into classes,
• means for calculating a first feature by using said matrix for feature extraction from said partial image classified into classes, and
• means for storing the data of said first feature, and
• said recognition means includes:
• means for receiving a second image including the object to be recognized,
• means for dividing said entered image into a second partial image,
• means for calculating a second feature by using a matrix for feature extraction from said partial image,
• means for calculating the similarity measure of the first image and second image by using said stored first feature data and second feature,
• means for recognizing the object in said second image by using said similarity measure, and
• means for issuing said result of recognition,
• wherein the means for entering the first image including the object to be learned is to enter plural pieces of image information mutually different in properties about one object to be learned, said learning means further includes a means for integrating said plural pieces of information and generating first integrated information, said first partial image includes said first integrated information, said means for entering the second image including the object to be recognized is to enter plural pieces of image information mutually different in properties about one object to be recognized, said recognizing means further includes a means for integrating said plural pieces of information and generating second integrated information, and said second partial image includes second integrated information.

A recording medium in which a computer program is recorded, being a recording medium of which program presents a method, being read by the computer and installed, for recognizing a specific object, said method having at least a learning step of learning a first entered image, and a recognition step of recognizing a second entered image, wherein said learning step includes:

• a step of entering the first image including the object to be learned,
• a step of dividing said entered image into a first partial image,
• a step of classifying said first partial image into plural classes,
• a step of calculating a matrix for feature extraction from said partial image classified into classes,
• a step of calculating a first feature by using said matrix for feature extraction from said partial image classified into classes, and
• a step of storing the data of said first feature, and
• said recognition step includes:
• a step of receiving a second image including the object to be recognized,
• a step of dividing said entered image into a second partial image,
• a step of calculating a second feature by using a matrix for feature extraction from said second partial image,
• a step of calculating the similarity measure of the first image and second image by using said stored first feature data and second feature,
• a step of recognizing the object in said second image by using said similarity measure, and
• a step of issuing said result of recognition,
• wherein the step of entering the first image including the object to be learned is to enter plural pieces of image information mutually different in properties about one object to be learned, said learning step further includes a step of integrating said plural pieces of information and generating first integrated information, said first partial image includes said first integrated information, said step of entering the second image including the object to be recognized is to enter plural pieces of image information mutually different in properties about one object to be recognized, said recognizing step further includes a step of integrating said plural pieces of information and generating second integrated information, and said second partial image includes second integrated information.
