The invention provides a dynamic
face analysis and identification method, device and
system based on a B / S mode. The dynamic
face analysis and identification method comprises that a
Web server sends an
uniform resource locator (URL) link of an ActiveX control with a
face detection and tracking function to a Web
client; the Web
client opens the URL link through a
web browser and downloads and installs the ActiveX control; a video
stream is read in dependence on the ActiveX control; the face in the video
stream is detected and tracked, after being acquired, a face image is return to the
Web server; when receiving the face image returned by the Web
client, the
Web server analyzes and identifies the face image, and obtains an analysis and identification result and sends the result to the Web client. In this way, a .
net framework does not need to be installed on the Web client, and the Web client can access the Web
server only based on the browser to achieve analysis and identification of face images, and therefore the user can use the dynamic
face analysis and
identification system conveniently, and the dynamic face analysis and
identification system is simple to maintain and low in cost.
