1. A livestock identification system comprising: (a) an image Capture Computer (ICC); (b) an image Processing Computer (IPC); (c) a livestock Web Server (LWS); (d) a livestock Image Database (LID); (e) a livestock Eigenface Database (LED); and (f) a livestock Historical Database (LHD); wherein said ICC is configured to capture animal image data (AID) of a livestock animal; said IPC is electrically coupled to say ICC and configured to receive said AID from said ICC; said IPC is configured to operate under control of machine instructions read from a computer readable medium; said ICC is configured to transmit said AID to said LWS over a Computer Communications Network (CCN); said LWS is configured to receive said AID and store said AID in said LID; said LWS is configured to convert said AID into an eigenface match vector (EMV) and compare said EMV against an eigenface weight vector (EWV) retrieved from said LED to determine if said livestock animal can be matched to said LED, and if so, generate a livestock animal identifier (LAI); said LWS is configured to retrieve information associated with said LAI from said LHD and determine the health or harvesting potential of the livestock animal associated with said LAI; and said LWS is configured to generate a report of said health or said harvesting potential via a web browser graphical user interface (GUI) operating on a remote computer system interacting with a user communicating with said LWS over a CCN.
