Grouping and ranking images based on facial recognition data

A system comprising a computing device and at least one program module that together are configured for performed actions comprising:

• receiving, for each image in a set of images, facial recognition data that, for each face detected in the image, comprises a face identifier that uniquely identifies the face, a set of facial feature descriptors, a face score that indicates an overall quality of the face, and a face signature that, across the images in the set, uniquely identifies an entity that the face represents;
• and
• grouping, based at least on the face signatures, images of the set into groups, where each group comprises one or more images that each show a detected face that represents a same entity as that represented by any other detected face shown in any image in the group.

At least one computer-readable media storing computer-executable instructions that, when executed by a computing device, cause the computing device to perform actions comprising:

• receiving, for each image in a set of images, facial recognition data that, for each face detected in the image, comprises a face identifier that uniquely identifies the face, a set of facial feature descriptors, a face score that indicates an overall quality of the face, and a face signature that, across the images in the set, uniquely identifies an entity that the face represents;
• and
• grouping, based at least on the face signatures, images of the set into groups, where each group comprises one or more images that each show a detected face that represents a same entity as that represented by any other detected face shown in any image in the group.
