PROCESS FOR THE ANALYSIS OF THE POSITIONING OF PRODUCTS ON STORE SHELVES
First Claim
1. A method for the analysis of the positioning of products on shelves based on a digital photograph of at least a part of the shelves, each product to be analyzed being predefined by a signature of visual characteristics of the said product, the method comprises the steps of:
- a. dividing of the digital photograph in zones comprising visually identical products, andb. for at least one zone,i. comparing the visual characteristics of the zone with the signatures of products, the comparison being based on a proximity metric of visual characteristics of the zone with the signatures of products andii. determination of the product(s) belonging to the zone are products having a signature minimizing the proximity metric.

Abstract
The invention concerns a method for the analysis of the positioning of products on shelves based on a digital photograph of at least a part of the shelves. Each product to be analyzed is predefined by a signature of visual characteristics of the product. The method includes the steps of dividing of the digital photograph in zones including visually identical products, and, for at least one zone, comparing the visual characteristics of the zone with the signatures of products. The comparison is based on a proximity metric of visual characteristics of the zone with the signatures of products. Finally, the determination is made as to which product(s) belonging to the zone are products having a signature minimizing the proximity metric.

9. A data structure representing a photograph wherein the structure comprises data fields representative of the zones of the photograph, each field allowing the definition the visual characteristics of the zone adapted for being compared with the signatures of the products in the form of a proximity metric of the visual characteristics of the zone with the signatures of the products.

10. A system for the analysis of the placement of products on shelves from a digital photo of at least a portion of the shelves, each product to be analysed being predefined by a signature of its visual characteristics, wherein the system comprises:
-
a. means for storing the signatures of the said products, b. means for dividing the digital photograph in zones comprising visually identical products, and c. for at least one zone, i. means of comparing visual characteristics of the zone with the signatures of products, the comparison being based on a proximity metric of visual characteristics of the zone with the signatures of the products, and ii. means of determining which of the products appearing in the zone are products having a signature minimizing the proximity metric.
