Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps: an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the following data: - a user name, - biometric data of said user acquired by said camera through a face recognition process, - additional personal data of said user, a finding step during which a wide image, acquired by said camera and embracing a wide area to encompass all potential users located in front of said display, is scanned in order to: - isolate at least two user's faces appearing on said wide image, - define a marking area surrounding each isolated face, - memorize the position of each of said marking areas in a register that identify said marking areas, a matching step during which each marking area is processed in order to: - extract biometric data of the face appearing inside said marking area, - match said extracted biometric data with the biometric data of the profiles stored in the database, and assign the detected profile ID with the marking area, while subsequent identification is requested by the application, executing the following steps: - acquiring a wide image with the camera, - extracting from the wide image an active area according to the marking area, - extracting for the active area the biometric data of a face, - starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, - transmitting the found profile ID to the application. an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the following data: - a user name, - biometric data of said user acquired by said camera through a face recognition process, - additional personal data of said user, - a user name, - biometric data of said user acquired by said camera through a face recognition process, - additional personal data of said user, a finding step during which a wide image, acquired by said camera and embracing a wide area to encompass all potential users located in front of said display, is scanned in order to: - isolate at least two user's faces appearing on said wide image, - define a marking area surrounding each isolated face, - memorize the position of each of said marking areas in a register that identify said marking areas, - isolate at least two user's faces appearing on said wide image, - define a marking area surrounding each isolated face, - memorize the position of each of said marking areas in a register that identify said marking areas, a matching step during which each marking area is processed in order to: - extract biometric data of the face appearing inside said marking area, - match said extracted biometric data with the biometric data of the profiles stored in the database, and assign the detected profile ID with the marking area, - extract biometric data of the face appearing inside said marking area, - match said extracted biometric data with the biometric data of the profiles stored in the database, and assign the detected profile ID with the marking area, while subsequent identification is requested by the application, executing the following steps: - acquiring a wide image with the camera, - extracting from the wide image an active area according to the marking area, - extracting for the active area the biometric data of a face, - starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, - transmitting the found profile ID to the application. - acquiring a wide image with the camera, - extracting from the wide image an active area according to the marking area, - extracting for the active area the biometric data of a face, - starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, - transmitting the found profile ID to the application.
