Abstract: A system and method for managing airtime on an out-of-home television network may include partitioning out-of-home television network airtime between a national network service provider and retailer local affiliate. Unbooked airtime may be reserved for a booking agent. In response to identifying the booking agent, the booking agent may be enabled to book reserved airtime on the out-of-home television network. Airtime may be booked with content in response to receiving a booking request. The content may be uploaded and distributed for display on the out-of-home television network.

Abstract: Clustering biometric templates is performed by determining fiduciary templates and cluster seed templates, both from a gallery of biometric templates. Similarity vectors are formed by comparing members of the cluster seed templates to the fiduciary templates. The gallery is then partitioned into clusters based upon the similarity vectors, and the clusters are populated from the remainder of the gallery. Partitioning may be performed by a classifier that implements a supervised machine learning algorithm that is trained with the similarity vectors, such as a multi-decision tree classification system. Matching may be accommodated by accessing a probe template, determining a cluster neighborhood for the probe template, and searching the cluster neighborhood to determine whether the gallery includes a match corresponding to the probe template. The same similarity metric is used both to partition a gallery into clusters, and in matching a probe template to the so-clustered gallery.

Abstract: A method and system for affixing covert identifying indicia to a digital image document, by altering pixel luminance and/or saturation in the image in selected areas of the image to a selected differential in luminance and/or saturation. The differential in luminance and/or saturation is selected to be in a range which is minimally detectable by the human eye. The identifying indicia may be detected by checking the digital document for patterns of differential luminance and/or saturation in the selected range of the differential.
