METHOD FOR COLLECTING INFORMATION ON USERS OF 4D LIGHT FIELD DATA, CORRESPONDING APPARATUSES AND COMPUTER PROGRAMS

摘要

A method for collecting information on users of light field data comprises:
- receiving Light Field viewing parameters (19) used for determining images (18) visualized by a user from light field data (14), along with an identifier of the user;
- storing the Light Field viewing parameters (19), along with an identifier of the light field data (14), in a user profile associated to the user's identifier. The light field data may be analyzed as a function of the Light Field viewing parameters (19) and of a light field acquisition device model, in order to identify objects in focus or objects not in focus in the visualized image. Identified objects are stored as objects of interest or of non-interest in the users' profile.
