Learning model for salient facial region detection
First Claim
1. A method comprising:
- receiving, via a processor, a first input image and a second input image, wherein each input image comprises a facial image of an individual;
for each input image;
based on a learning based model trained to learn different facial features relevant to different facial image analysis tasks and further trained to distinguish different facial regions that include the different facial features, determining, via the processor, a corresponding first set of facial regions of the facial image and a corresponding second set of facial regions of the facial image, wherein the corresponding first set of facial regions comprises at least one facial region including one or more age-invariant facial features, and the corresponding second set of facial regions comprises at least one other facial region including one or more age-sensitive facial features; and
performing, via the processor, at least one of the different facial image analysis tasks based on at least one facial feature extracted from at least one set of facial regions.

Abstract
One embodiment provides a method comprising receiving a first input image and a second input image. Each input image comprises a facial image of an individual. For each input image, a first set of facial regions of the facial image is distinguished from a second set of facial regions of the facial image based on a learning based model. The first set of facial regions comprises age-invariant facial features, and the second set of facial regions comprises age-sensitive facial features. The method further comprises determining whether the first input image and the second input images comprise facial images of the same individual by performing face verification based on the first set of facial regions of each input image.

9. A system, comprising:
-
at least one processor; and a non-transitory processor-readable memory device storing instructions that when executed by the at least one processor causes the at least one processor to perform operations including; receiving a first input image and a second input image, wherein each input image comprises a facial image of an individual; for each input image; based on a learning based model trained to learn different facial features relevant to different facial image analysis tasks and further trained to distinguish different facial regions that include the different facial features, determining a corresponding first set of facial regions of the facial image and a corresponding second set of facial regions of the facial image, wherein the corresponding first set of facial regions comprises at least one facial region including one or more age-invariant facial features, and the corresponding second set of facial regions comprises at least one other facial region including one or more age-sensitive facial features; and performing at least one of the different facial image analysis tasks based on at least one facial feature extracted from at least one set of facial regions. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer readable storage medium including instructions to perform a method comprising:
-
receiving a first input image and a second input image, wherein each input image comprises a facial image of an individual; for each input image; based on a learning based model trained to learn different facial features relevant to different facial image analysis tasks and further trained to distinguish different facial regions that include the different facial features, determining a corresponding first set of facial regions of the facial image and a corresponding second set of facial regions of the facial image, wherein the corresponding first set of facial regions comprises at least one facial region including one or more age-invariant facial features, and the corresponding second set of facial regions comprises at least one other facial region including one or more age-sensitive facial features; and performing at least one of the different facial image analysis tasks based on at least one facial feature extracted from at least one set of facial regions. - View Dependent Claims (16, 17, 18, 19, 20)
