Claim:
1. A system to annotate media content, comprising: a pattern recognition system (PRS) having an initial set of input parameters that generates PRS output metadata associated with a frame of a media stream; an archive for storing ground truth metadata (GTM) associated with the same frame of the media stream; a device to merge the GTM and the PRS output metadata and thereby generate proposed annotation data (PAD); and a user interface for use by a human annotator (HA) including an editor and an input device to approve or edit the PAD for the frame; and an optimization system to adjust input parameters for the PRS to minimize a single distance metric corresponding to a difference between the GTM and PRS output metadata, wherein each type of GTM is compared to a corresponding type of the PRS output metadata to generate a plurality of distance metrics by type, wherein the single distance metric is computed by combining the plurality of distance metrics by type, and wherein one type of the PRS output metadata includes spatial position.
