Abstract
A system and method for concealing and revealing a human face in media objects may include obtaining a first media object capturing an image of the face; employing a first unit to: extract, from the first media object, a set of features representing the face, and generate a second media object, by embedding the extracted features in an anonymized media object; and employing a second unit to recognize the face based on the second media object.
Claims19
A method of concealing and revealing a human face in images, the method comprising:
- obtaining a first image of the face;
- employing a first unit to:
- extract, from the first image of the face, a set of features representing the face, and
- generate a second image by inserting pixels in an anonymized image, such that the inserted pixels represent the extracted features wherein perceptual differences between the second image and the anonymized image are minimized by the first unit;
- and
- employing a second unit to extract at least some of the inserted pixels from the second image and recognize the face based on the extracted inserted pixels.
A non-transitory computer readable medium comprising instructions which, when executed by a processor, cause the processor to implement the method of:
- obtaining a first image of the face;
- employing a first unit to:
- extract, from the first image of the face, a set of features representing the face, and
- generate a second image, by inserting pixels in an anonymized image, such that the inserted pixels represent the extracted features wherein perceptual differences between the second image and the anonymized image are minimized by the first unit;
- and
- employing a second unit to extract at least some of the inserted pixels from the second image recognize the face based on the extracted inserted pixels.
A system for concealing and revealing a human face in images, the system comprising:
- a memory;
- and
- a processor configured to:
- obtain a first image of the face;
- employ a first unit to:
- extract, from the first image of the face, a set of features representing the face, and
- generate a second image, by inserting pixels in an anonymized image, such that the inserted pixels represent the extracted features wherein perceptual differences between the second image and the anonymized image are minimized by the first unit;
- and
- employ a second unit to extract at least some of the inserted pixels from the second image and recognize the face based on the inserted pixels.
