Scalable face image retrieval
First Claim
Patent Images
1. A method comprising:
- receiving an image at a computing device;
detecting a face in the image by the computing device;
identifying a plurality of facial components of the detected face in the image by the computing device;
generating a plurality of visual words from the identified plurality of facial components by the computing device;
comparing the generated plurality of visual words from the identified facial components with a plurality of stored visual words by the computing device, wherein each visual word is associated with one of a plurality of stored images;
determining a plurality of candidate matching images from the plurality of stored images based on the comparison by the computing device;
selecting a plurality of reference images from the plurality of candidate matching images by the computing device;
for each candidate matching image of the plurality of candidate matching images, determining a distance between the candidate matching image and each reference image of the plurality of reference images by the computing device; and
ranking the candidate matching images based on the determined distances by the computing device.

Abstract
A system for identifying individuals in digital images and for providing matching digital images is provided. A set of images that include faces of known individuals is received. Faces are detected in the images and facial components are identified in each face. Visual words corresponding to the facial components are generated, stored, and associated with identifiers of the individuals. At a later time, a user may provide an image that includes the face of one of the known individuals. Visual words are determined from the face of the individual in the provided image and matched against the stored visual words. Images associated with matching visual words are ranked and presented to the user.

7. A method comprising:
-
receiving a plurality of images by a computing device, wherein each image includes a face associated with an individual; detecting the face in each of the plurality of images by the computing device; identifying a plurality of facial components for each detected face by the computing device; generating a plurality of visual words from the identified plurality of facial components of each detected face by the computing device; for each generated plurality of visual words, storing the generated plurality of visual words by the computing device; receiving an image by the computing device, wherein the image is not part of the plurality of images; determining a plurality of candidate matching images from the plurality of images for the received image by the computing device; selecting a plurality of reference images from the plurality of candidate matching images by the computing device; for each candidate matching image of the plurality of matching images, determining a distance between the candidate matching image and each reference image of the plurality of reference images by the computing device; and ranking the candidate matching images based on the determined distances by the computing device. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system comprising:
-
at least one computing device; a training component that; receives a plurality of images, wherein each image includes a face associated with an individual; detects the face in each of the plurality of images; for each detected face, identifies a plurality of facial components of the detected face; for each identified facial component, generates a plurality of visual words from the identified facial component of the detected face; and for each generated plurality of visual words, stores the generated plurality of visual words with an identifier of the individual associated with the detected face included in the image and an identifier of the image; and a matching component that; receives an image, wherein the image is not part of the plurality of images; detects a face in the image; identifies a plurality of facial components of the detected face in the image; generates a plurality of visual words from the identified plurality of facial components; compares the generated plurality of visual words from the identified facial components with the plurality of stored visual words; determines a plurality of candidate matching images from the plurality of images for the received image based on the comparison; selects a plurality of reference images from the plurality of candidate matching images; for each candidate matching image of the plurality of matching images, determines a distance between the candidate matching image and each reference image of the plurality of matching images; and ranks the candidate matching images based on the determined distances. - View Dependent Claims (14, 15, 16, 17)
