System and method of weighting to a common use of descriptors of the image

摘要

The present invention relates to a process and a system for generating a representation of the image which comprises the generation of a set of descriptors integrated, comprising, for each of a set of areas of an image, the extraction (s106) of a descriptor of a zone which is representative of the pixels in the zone and the integration (s108) of the descriptor of the zone in a multidimensional space in order to form a descriptor integrated. A representation of the image is generated by the aggregation of the assembly of descriptors integrated (s110). In the aggregation, each descriptor is weighted with a respective weights in a set of weight, the assembly of the weight being calculated on the basis of the descriptors of the zone for the image. Information based on the representation of the image are produced at the output (s114). At least one of the extraction of descriptors of the zone, the integration of the descriptors of the zone, and the generation of the representation of the image is carried out with a computer processor.
