Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Fig. 1 is the method flow diagram of the embodiment of the present invention one, comprising:
Step 101, Face datection is carried out to the personage in the preview screen of capture；
