Method, terminal, and storage medium for tracking facial critical area

A terminal, comprising:

• a memory, storing computer readable instructions, and
• a processor, coupled to the memory and configured for:
• accessing a frame of image in a video file;
• obtaining coordinate frame data of a facial part in the image by detecting a position of the facial part in the frame of the image;
• determining initial coordinate frame data of a critical area in the facial part according to the coordinate frame data of the facial part;
• obtaining coordinate frame data of the critical area according to the initial coordinate frame data of the critical area in the facial part;
• accessing an adjacent next frame of image in the video file;
• obtaining initial coordinate frame data of the critical area in the facial part for the adjacent next frame of image by using the coordinate frame data of the critical area in the frame;
• and
• obtaining coordinate frame data of the critical area for the adjacent next frame of image according to the initial coordinate frame data of the critical area in the adjacent next frame of image.

A non-transitory computer readable storage medium storing computer-executable instructions for, when being executed, one or more processors to perform a facial critical area tracking method, the method comprising:

• accessing a frame of image in a video file;
• obtaining coordinate frame data of a facial part in the image by detecting a position of the facial part in the frame of the image;
• determining initial coordinate frame data of a critical area in the facial part according to the coordinate frame data of the facial part;
• obtaining coordinate frame data of the critical area according to the initial coordinate frame data of the critical area in the facial part;
• accessing an adjacent next frame of image in the video file;
• obtaining initial coordinate frame data of the critical area in the facial part for the adjacent next frame of image by using the coordinate frame data of the critical area in the frame;
• and
• obtaining coordinate frame data of the critical area for the adjacent next frame of image according to the initial coordinate frame data of the critical area in the adjacent next frame of image.
