System for producing compliant facial images for selected identification documents
A method of recoding a photograph for use in a personal photo identification document such as a passport includes using a digital image capture system, including a digital camera, a computer processor, and memory to store specifications and requirements for a photo print in order to be compliant for use in a user selected photo ID such as a passport for a selected country or jurisdiction, using the digital image capture system to capture a facial image, using facial image processing techniques to provide automatic detection of a face and facial feature points on the facial image, processing the facial image and generating a visual indication of compliance, and when compliant, generating the photograph based on the compliant facial image.
1. A method of recording a photograph for use in a personal photograph identification document (“photo ID”) comprising:
using a digital image capture system, including a computer processor and memory, to store specifications for a photograph, the specifications defining photo ID compliance requirements for a selected photo ID jurisdiction;
receiving a sequence of facial images;
using facial image processing techniques to automatically detect a face and facial feature points on each image in the sequence of facial images;
assigning an aggregate compliance score to each image in the sequence of facial images, wherein the aggregate compliance score is a measure of fulfilling the photo ID compliance requirements for the selected photo ID jurisdiction;
presenting at least one image that meets a minimum aggregate compliance score; and
modifying the at least one presented image to improve compliance with the photo ID compliance requirements for the selected photo ID jurisdiction by automatically adjusting one of a determined set of image characteristics, wherein the determined set of image characteristics includes an in-plane rotation, a crop, an exposure, a color balance, an illumination, and a background color.
2. The method of claim 1 wherein the sequence of facial images is received from a video stream or a video file.
3. The method of claim 1 wherein the photo ID comprises a passport.
4. The method of claim 1 wherein presenting the at least one image that meets the minimum aggregate compliance score comprises presenting an image that has a highest aggregate compliance score in the sequence of facial images.
5. The method of claim 1 wherein modifying the at least one presented image includes automatically adjusting zoom.
6. The method of claim 1 wherein the specifications are automatically adjusted based on demographic information of the selected photo ID jurisdiction.
7. A method of recording a photograph for use in a personal photo identification document (“photo ID”) comprising:
using a digital image capture system, including a digital camera, computer processor and memory, to store specifications for a photograph, the specifications defining photo ID compliance requirements for a selected photo ID jurisdiction; and
receiving, from the digital camera, a sequence of facial images of a subject, and, for each facial image in the sequence:
using facial image processing techniques to automatically detect a face and facial feature points on the facial image;
modifying a selected facial image to improve compliance with the photo ID compliance requirements for the selected photo ID jurisdiction by automatically adjusting one of a determined set of image characteristics, wherein the determined set of image characteristics includes an in-plane rotation, a crop, an exposure, a color balance, an illumination, and a background color;
generating instructions to correct facial image defects present in the selected facial image, wherein the instructions direct the subject to correct the facial image defects that cannot be automatically corrected;
determining whether the selected facial image fulfills the photo ID compliance requirements for the selected photo ID jurisdiction; and
when compliant, recording the selected facial image for use as the photograph in the photo ID.
8. The method of claim 7 wherein the photo ID comprises a passport.
9. The method of claim 7 wherein modifying the selected facial image comprises automatically adjusting zoom.
10. The method of claim 7 wherein modifying the selected facial image comprises automatically adjusting an external light source associated with the digital image capture system.
11. The method of claim 7 wherein the specifications automatically adjusted based on demographic information of the selected photo ID jurisdiction.
12. A method of recording a photograph for use in a personal photo identification document (“photo ID”) comprising:
using a digital image capture system, including a digital camera, a computer processor, and memory to store specifications for a photo print, the specifications defining photo ID compliance requirements for a selected photo ID jurisdiction;
using the digital image capture system to capture a facial image;
using facial image processing techniques to automatically detect a face and facial feature points on the facial image;
determining whether the facial image fulfills the photo ID compliance requirements for the selected photo ID jurisdiction, wherein determining comprises analyzing at least one bio-metric element associated with the facial image;
modifying the facial image to improve compliance with the photo ID compliance requirements for the selected photo ID jurisdiction by automatically adjusting one of a determined set of image characteristics, and wherein the determined set of image characteristics includes an in-plane rotation, a crop, an exposure, a color balance, an illumination, and a background color;
generating instructions to guide a subject of the facial image to correct deficits that cannot be automatically corrected;
generating a visual compliance indication when the facial image fulfills the photo ID compliance requirements for the selected photo ID jurisdiction; and
when compliant, generating the photograph based on the compliant facial image.
13. The method of claim 12 , wherein analyzing the at least one bio-metric element comprises analyzing at least one of head scale and position, head pose, openness of the eyes, appearance of the mouth, and gaze associated with the facial image.
14. The method of claim 12 , wherein determining whether the facial image fulfills the photo ID compliance requirements for the selected photo ID jurisdiction comprises a tiered analysis of a plurality of facial attributes.
15. The method of claim 12 , wherein analyzing the at least one bio-metric element further comprises a tiered analysis of a plurality of bio-metric attributes.
16. The method of claim 12 , wherein the photo ID comprises a passport.
17. The method of claim 12 , wherein modifying the facial image comprises automatically adjusting zoom.
18. The method of claim 12 wherein the specifications are automatically adjusted based on demographic information of the selected photo ID jurisdiction.
19. The method of claim 12 wherein modifying the facial image comprises automatically adjusting an external light source associated with the digital image capture system.
