1. A method of identifying a retail product, based at least in part on assessing correspondence between image recognition features associated with the retail product and image recognition features associated with a collection of reference products, the method including the acts:

  • receiving plural recognition features derived from imagery associated with the retail product;

    using a hardware processor configured with software, distinguishing a subset of the received features that are associated with a logo, said logo being present on plural of said reference products; and

    taking an action in response to said distinguishing, wherein said action comprises at least one of;

    (a) providing, via a user interface of a camera-equipped portable device that captured said imagery of the retail product, information indicating that the camera should be moved further away from the product, so as to capture a wider field of view;

    (b) weighting said subset of received features less than other of the received features, in determining a match between the retail product and one of said reference products;

    (c) disregarding said subset of received features in determining a match between the retail product and one of said reference products;

    (d) disregarding features other than said subset of features, and identifying plural reference products having said logo;

    or(e) treating said determined subset of received features differently than others of the received features, in identifying one or more reference products.
