Methods, devices and computer programs for processing images in a system comprising a plurality of cameras

A device for optimizing processing of at least two images obtained from at least two sources of images, a sub-image of each of the at least two images representing an overlapping area of a real scene, the device comprising a processor configured for carrying out the steps of:

• generating a two-dimensional (2D) map representing the overlapping area of the real scene;
• partitioning the overlapping area of the generated 2D map into a plurality of sub-areas as a function of an occlusion criterion determined for each point of the overlapping area;
• associating an identifier of a source of images with each point of the generated 2D map, the associating step being based on the occlusion criterion or on a detection score depending on the sub-areas;
• and
• generating a 2D role map based on the generated 2D map and on the associated identifiers, the 2D role map comprising a plurality of parts, all the points of each part of the 2D role map being associated with a single identifier of a source of images so that only one of the at least two sources of images is to be selected to process a representation of a portion of the overlapping area.

A method for optimizing processing of at least two images obtained from at least two cameras, the method comprising:

• generating an overlapping area of a real scene among at least two cameras;
• determining an occlusion criterion in the overlapping area;
• generating a two-dimensional (2D) occlusion map based on the occlusion criterion;
• and
• generating a 2D role map based on the generated 2D occlusion map so that one of the at least two cameras is to be selected to process a representation of a portion of the overlapping area.
