Abstract

The present disclosure relates to a method, adapted to be implemented in an electronic device, for selecting a content, during a backup operation, amongst a plurality of contents coding audiovisual data and being accessible by the electronic device. According to one embodiment, the method includes obtaining, for each accessible content, one audiovisual descriptor derived from the audiovisual data, and selecting the accessible content according to one backup rule taking into account the obtained audiovisual descriptor. The present disclosure also relates to corresponding electronic device, system, computer readable program product and computer readable storage medium.

First claim

1 . A method, adapted to be implemented in an electronic device, for selecting at least one content, during a backup operation, amongst a plurality of contents coding audiovisual data and being accessible by said electronic device, said method comprising
obtaining, for each accessible content, at least one audiovisual descriptor derived from said audiovisual data; selecting said accessible content according to at least one backup rule taking into account said obtained audiovisual descriptor of said accessible contents.

2 . The method according to claim 1 , wherein said at least one backup rule comprises at least one criterion belonging to a group comprising:
a quality of said audiovisual data; a presence of at least one face in said accessible content; a presence of at least one known face in said accessible content; a presence of at least one known place in said accessible content; a similarity between said accessible content and another of said accessible contents; a privacy of said accessible content.

3 . The method according to claim 2 wherein said group further comprises:
a size limit of said accessible content;
a backup state of a similar accessible content;
a format or a version of said accessible content;
a time stamp value of an obtaining, an acquisition, and/or a modification of said accessible content;
a geo-localization of an acquisition of said accessible content;
a date of a former backup operation,
a result of a former backup operation,
a number of accessible contents obtained, modified or created since the last backup operation,
a maximum number of contents to be backed up.

4 . The method according to claim 1 , wherein said backup rule is acquired from a user interface of said electronic device.

5 . The method according to claim 1 , wherein said at least one audiovisual descriptor relates to at least one element belonging to a group comprising:
a distribution of intensities inside at least a part of said accessible content, a distributions of colors inside at least a part of said accessible content; a visual and/or audio pattern inside at least a part of said accessible content; a distance between at least two frames of said accessible content; a valence attribute; an arousal attribute; an acquisition focal length of said accessible content; an acquisition speed of said accessible content; a detected face; a perceptual characteristic of the coded data.

6 . The method according to claim 1 , wherein said method comprises copying said selected content from at least one source device from which said selected content is accessible.

7 . The method according to claim 1 , wherein said method comprises backing up said selected content on at least one destination device.

8 . An electronic device comprising at least one memory and at least one processor adapted for selecting at least one content, during a backup operation, amongst a plurality of contents coding audiovisual data and being accessible from said electronic device, wherein at least one of said processor is adapted for:
obtaining, for each accessible content, at least one audiovisual descriptor derived from said audiovisual data; selecting said accessible content according to at least one backup rule taking into account said obtained audiovisual descriptor of said accessible contents.

9 . The electronic device according to claim 8 wherein at least one of said processor is adapted for obtaining at least one contextual descriptor of at least one electronic device involved in said backup operation and said backup rule takes into account said contextual descriptor of said involved electronic device.

10 . The electronic device according to claim 8 wherein said involved electronic device is said electronic device itself, a source device from which said content is accessible to said electronic device, and/or a destination device where said content is to be backed up during said backup operation.

11 . The electronic device according to claim 10 , wherein said electronic device is distinct from said source and/or said destination device.

12 . The electronic device according to claim 8 , wherein said at least one backup rule comprises at least one criterion belonging to a group comprising:
a quality of said audiovisual data; a presence of at least one face in said accessible content; a presence of at least one known face in said accessible content; a presence of at least one known place in said accessible content; a similarity between said accessible content and another of said accessible contents; a privacy of said accessible content.

13 . The electronic device according to claim 8 , wherein said backup rule is acquired from a user interface of said electronic device.

14 . The electronic device according to claim 8 , wherein said at least one audiovisual descriptor relates to at least one element belonging to a group comprising:
a distribution of intensities inside at least a part of said accessible content, a distributions of colors inside at least a part of said accessible content; a visual and/or audio pattern inside at least a part of said accessible content; a distance between at least two frames of said accessible content; a valence attribute; an arousal attribute; an acquisition focal length of said accessible content; an acquisition speed of said accessible content; a detected face; a perceptual characteristic of the coded data.

15 . The electronic device according to claim 8 , wherein said at least one processor is adapted for copying said selected content from at least one source device from which said selected content is accessible.

16 . The electronic device according to claim 8 , wherein said at least one processor is adapted for backing up said selected content on at least one destination device.

17 . A system comprising
at least one source device, giving access to at least one content coding audiovisual data; an electronic device comprising at least one memory and at least one processor configured for selecting at least one content, during a backup operation, amongst said accessible contents, said system being characterized in that at least one of said processor of said electronic device is adapted for: obtaining, for each accessible content, at least one audiovisual descriptor derived from said audiovisual data; selecting said accessible content according to at least one backup rule taking into account said obtained audiovisual descriptor of said accessible contents.

18 . The system according to claim 17 wherein said system further comprises at least one destination device where at least one of said selected content is to be at least partially backup during said backup operation.

19 . A non-transitory computer readable program product, characterized in that it comprises program code instructions for performing the method according to claim 1 , when said non-transitory software program is executed by a computer.

20 . Computer readable storage medium carrying a software program characterized in that it comprises program code instructions for performing the method according to claim 1 , when said non-transitory software program is executed by a computer.
