To　retrieval　directly　information　with　images,　by　using　the　face　detection　technique　based　on　the　gravity-center　template　matching　method　and　the　face　recognition　technique　based　on　methods　of　the　principal　component　analysis　and　the　linear　discriminative　analysis.　To　the　given　video　sequence,　the　system　can　retrieve　face　image　from　big　face　image　database　on　time.　Experimental　results　show　that　the　system　is　provided　with　good　human-machine　interface,　high　retrieval　rate,　short　retrieval　time　and　can　well　satisfy　the　user＇s　requirements.
