Abstract: Genre or theme assignment data (104) for a program in a digital television or other data transmission is recovered by a receiver (100) and mapped to a genre in a standardized genre assignment schedule (240). A country associated with the transmission is identified, such as by obtaining a country code (105) from the digital data transmission, or via a receiver setting. A genre assignment schedule is identified based on the country. Data, such as user nibbles (220) or standard content nibbles (230), is obtained from the transmission to identify the original genre and assign the program to a corresponding standardized genre.

Abstract: Optimizing example-based computer-aided diagnosis (CADx) is accomplished by clustering volumes-of-interest (VOIs) (116) in a database (120) into respective clusters according to subjective assessment of similarity (S220). An optimal set of volume-of-interest (VOI) features is then selected for fetching examples such that objective assessment of similarity, based on the selected features, clusters, in a feature space, the database VOIs so as to conform to the subjectively-based clustering (S230). The fetched examples are displayed alongside the VOI to be diagnosed for comparison by the clinician. Preferably, the displayed example is user-selectable for further display of prognosis, therapy information, follow up information, current status, and/or clinical information retrieved from an electronic medical record (S260).
