Abstract: A method for clustering groups of photographs, wherein users are each identified by a unique identifier, each user photographs. The method includes capturing photographs; assigning, to each captured photograph, at least one metadata defined by a type, comparing the metadata assigned to each photograph to determine at least one discriminant type, grouping at least two photographs by discriminant type of metadata and clustering the groups if the number of photographs is superior to a first predefined limit value. The method further includes determining a degree of similarity of a cluster of photographs depending on metadata, and defining a common cluster among the users if the degree of similarity is superior to a second predefined limit value.

Abstract: A method for clustering at least two groups of photographs, wherein at least two users are each identified by a unique identifier, the unique identifiers of said users being associated in at least one memory, each user having at least two photographs comprising: for each user: a step of capturing at least two photographs; a step of assigning, to each captured photograph, at least one metadata defined by a type, a step of comparing the metadata assigned to each photograph to determine at least one discriminant type, a step of grouping at least two photographs by discriminant type of metadata, a step of comparing the number of photographs in a group to a first predefined limit value, wherein, if the number of photographs in the group is superior to the first predefined limit value, a step of clustering the photographs of the group is performed, then, for at least one user: step of determining a degree of similarity of a cluster of photographs from one of the users to a cluster of photographs from another o

Abstract: A method for sharing a photograph between at least two users identified by a unique identifier on a network, the method comprising: a step of capturing a photograph by a first user; a step of extracting metadata from the photograph captured; a step of calculating a photograph interaction rating depending on data representative of the first user and each other user and on the extracted photograph metadata; a step of comparing the photograph interaction rating of the pairs of users to a first predefined limit value; if the photograph interaction rating is superior to the first predefined limit value, a step of initializing a contact between said users upon validation by the first user.

Abstract: A method for retrieving at least two captured photographs, the method comprising: a step of capturing at least two photographs; a step of extracting metadata from the photograph captured; a step of displaying on a screen: at least one thumbnail representing at least one photograph on a first part of the screen and at least one icon representing the extracted metadata on a second part of the screen parallel to the first part, the icon representing the extracted metadata corresponding to at least two photographs; a step of moving the at least one thumbnail and icon displayed upon action by a user on the screen, the movement of the icons being proportional and simultaneous to the movement of the thumbnails.
