Association and prediction in facial recognition

摘要

Some implementations provide techniques and arrangements to address intrapersonal variations encountered during facial recognition. For example, some implementations employ an identity data set having a plurality of images representing different intrapersonal settings. A predictive model may associate one or more input images with one or more images in the identity data set. Some implementations may use an appearance-prediction approach to compare two images by predicting an appearance of at least one of the images under an intrapersonal setting of the other image. Further, some implementations may utilize a likelihood-prediction approach for comparing images that generates a classifier for an input image based on an association of an input image with the identity data set.

1. A method comprising:
under control of one or more processors configured with executable instructions, determining a first intrapersonal setting of at least a portion of a first input image; determining a second intrapersonal setting of at least a portion of a second image; determining, based at least in part on a threshold for a difference between the first intrapersonal setting and the second intrapersonal setting, whether the first input image and the second image are comparable with each other for direct appearance matching; and in response to determining that the first input image and the second image are not comparable with each other for direct appearance matching:
identifying a plurality of images of an identity data set that are associated with a different identity than an identity associated with the first input image;identifying a nearest match between the at least the portion of the first input image and at least a portion of a first generic image of the plurality of images, wherein the first generic image is associated with a generic identity;transforming the first input image into a third image by substituting at least a portion of a second generic image of the plurality of images with the at least the portion of the first input image, wherein the second generic image is associated with the generic identity; andperforming direct appearance matching between the second image and the third image.
