This invention relates to media targeting systems and, in particular, to a system for customizing the digital advertising that is displayed to viewers in public spaces based on using visual pattern recognition techniques in association with previous retail transactions as the basis for building a targeting database and delivering targeted advertising.

2. Description of the Related Art
Digital Signage is an emerging visual advertising medium which utilizes digital displays deployed into public spaces, connected through a wide area network, which display visual advertising messages to individuals within the visual range of the display (“local traffic”). The advertising media takes the form of digital files which are distributed electronically over the network to the remote display system to be run on the display in accordance with some predetermined criteria.
Early implementations of Digital Signage used a simple media loop in which a number of still images (“media segments”) would be displayed in series, each for a period of time, and the cycle would be continuously repeated throughout the day. In this mode, the advertising medium took on the same basic characteristics as traditional static poster advertising except that the ads could be more readily distributed and more highly multiplexed. In spite of these advantages, the display site did not increase the total media value sufficiently to overcome the increased costs of deploying and maintaining the Digital Signs.
In response to this problem, there have been efforts to design “media targeting” systems which tailor the media segments more specifically to the characteristics of the local traffic of a particular display at a given moment, as opposed to running the same loop continuously on all of the displays. By doing so, the total media
