Face location tracking method, apparatus, and electronic device

A computer-implemented method for tracking locations of a face across a plurality of images comprising a first image and a second image, the method comprising:

• determining a first face region within the first image, the first face region including the location of the face within the first image;
• based on the determined first face region within the first image, determining a predicted face region within the second image;
• determining a first region of similarity within the predicted face region, the first region of similarity having at least a predetermined degree of similarity to the first face region within the first image;
• determining whether a second face region is present within the second image;
• and
• determining the location of the face within the second image based on (i) the first region of similarity, (ii) the determination of whether the second face region is present within the second image, and (iii) a face region selection rule.

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• determining a first face region within a first image, the first face region including a location of a face within the first image;
• based on the determined first face region within the first image, determining a predicted face region within a second image;
• determining a first region of similarity within the predicted face region, the first region of similarity having at least a predetermined degree of similarity to the first face region within the first image;
• determining whether a second face region is present within the second image;
• and
• determining the location of the face within the second image based on (i) the first region of similarity, (ii) the determination of whether the second face region is present within the second image, and (iii) a face region selection rule.

A system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
• determining a first face region within a first image, the first face region including a location of a face within the first image;
• based on the determined first face region within the first image, determining a predicted face region within a second image;
• determining a first region of similarity within the predicted face region, the first region of similarity having at least a predetermined degree of similarity to the first face region within the first image;
• determining whether a second face region is present within the second image;
• and
• determining the location of the face within the second image based on (i) the first region of similarity, (ii) the determination of whether the second face region is present within the second image, and (iii) a face region selection rule.
