Abstract
A method for verifying a face by an electronic device is described. The method includes obtaining a partial face depth map from a depth sensor. The partial face depth map does not include information for an entire face. The method also includes performing a first alignment of the partial face depth map with full face data in a gallery. The method further includes performing a second alignment of the partial face depth map and the full face data based on the first alignment. The method additionally includes verifying whether the partial face depth map matches the full face data based on the second alignment.
Claims20
A method for verifying a face by an electronic device, comprising:
- obtaining a partial face depth map from a depth sensor, wherein the partial face depth map does not include information for an entire face;
- performing a first alignment of the partial face depth map with full face data in a gallery;
- performing a second alignment of the partial face depth map and the full face data based on the first alignment;
- and
- verifying whether the partial face depth map matches the full face data based on the second alignment.
An electronic device for verifying a face, comprising:
- a depth sensor configured to obtain a partial face depth map, wherein the partial face depth map does not include information for an entire face;
- a processor coupled to the depth sensor, wherein the processor is configured to perform a first alignment of the partial face depth map with full face data in a gallery, to perform a second alignment of the partial face depth map and the full face data based on the first alignment, and to verify whether the partial face depth map matches the full face data based on the second alignment.
A computer-program product for verifying a face, comprising a non-transitory tangible computer-readable medium having instructions thereon, the instructions comprising:
- code for causing an electronic device to obtain a partial face depth map from a depth sensor, wherein the partial face depth map does not include information for an entire face;
- code for causing the electronic device to perform a first alignment of the partial face depth map with full face data in a gallery;
- code for causing the electronic device to perform a second alignment of the partial face depth map and the full face data based on the first alignment;
- and
- code for causing the electronic device to verify whether the partial face depth map matches the full face data based on the second alignment.
