  • Patent number: 10997398
    Abstract: An information processing apparatus generates authentication data that can be used for authentication of a first object that is included in a captured image captured by a first image capturing apparatus and has been authenticated by a first authentication apparatus corresponding to the first image capturing apparatus; and causes the authentication data to be reflected to an authentication database (DB) of at least one authentication apparatus included in a plurality of authentication apparatuses. The apparatus generates second authentication data corresponding to a second capturing condition differing from a first capturing condition corresponding to first authentication data that is included in the authentication DB of the first authentication apparatus and was used when authenticating the first object.

  • Patent number: 10147018
    Abstract: There is provided with an image processing apparatus. An evaluation is set for each of the pairs. The evaluation is set based on at least one of the number of feature points in the first image where local feature amounts are similar to a local feature amount at one of the pair or the number of feature points in the second image where local feature amounts are similar to a local feature amount at one of the pair, in such a manner that the smaller the number of feature points, the higher the evaluation. A similarity between the first image and the second image is determined using a RANSAC method. A pair having a high evaluation is used with priority in derivation of a function for transforming coordinates using the RANSAC method.

  • Patent number: 10055822
    Abstract: A tint of an object according to a second image capturing device is corrected by a first parameter for correcting a tint of a second object that the second image capturing device captured in a first time zone to a tint of a first object that a first image capturing device captured in a first time zone. If a third object captured by a third image capturing device corresponds to the first object, a parameter for correcting a tint of the third object to the tint of the first object is used for correcting a tint of an object according to a third image capturing device. If the third object corresponds to the second object, the first parameter and a third parameter for correcting the tint of the third object to the tint of the second object is used for the foregoing tint correction.
