Method and device of registering face based on video data, and electronic whiteboard

A method of registering a face based on video data, comprising:

• receiving video data;
• acquiring a first image frame sequence from the video data, wherein each image frame in the first image frame sequence comprises a face detection frame containing a complete facial feature of a face;
• determining, according to a relative position of the face detection frame in each image frame, whether the image frame reaches a preset definition or not;
• extracting a plurality of sets of facial features based on an image information of a plurality of face detection frames in response to determining that the image frame reaches the preset definition, and determining whether the face represents an object or not according to the plurality of sets of facial features, wherein the object is a person;
• and
• registering the object according to the first image frame sequence in response to determining that the face represents the object;
• wherein the registering the object according to the first image frame sequence comprises:
• registering the object by using a designated image frame in the first image frame sequence as registration data;
• wherein the acquiring a first image frame sequence from the video data comprises:
• acquiring a plurality of image frames from the video data according to a sequence of capturing a video;
• determining whether the plurality of image frames contains a face or not based on a face detection model;
• and
• determining a face detection frame containing the face in each image frame of the plurality of image frames, in response to determining that the image frame contains the face;
• and
• wherein the acquiring a first image frame sequence from the video data further comprises:
• determining whether the image frame acquired contains a complete facial feature or not;
• storing the image frame as a frame in the first image frame sequence in response to determining that the image frame contains the complete facial feature;
• and
• ending the acquiring of image frames in response to determining that a predetermined number of image frames are stored in the first image frame sequence.
