  • Patent number: 11657652
    Abstract: Methods, systems, and computer-readable storage media for determining that a subject is a live person include obtaining a first image captured using a first camera disposed on a first side of a mobile device and obtaining a second image captured using a second camera disposed on a second side of the mobile device that is on the opposite side of the first side. The first image includes a representation of reflections visible on the corneas of a subject. The first image and the second image are pre-processing to generate a third image and a fourth image, respectively, where a first field of view represented in the third image at least partially overlaps with a second field of view of the fourth image. A determination is made, based on the third and fourth images, that a scene represented in the first field of view is substantially same as a scene represented in the second field of view.

  • Patent number: 11373283
    Abstract: An object monitoring device 1 comprises an imaging device 2 capturing an image of a range in which a predetermined object should be present and generating an image, an object recognizing part 34 recognizing the object based on the image, a detecting part 35 detecting that the image is unclear, a storage part 31 storing detection information showing that it has been detected that the image is unclear, and a judging part 36 judging a cause for the object not being recognized when the object is not recognized based on the image. When a state occurs where the object is not recognized based on the image and it is not detected that the image is unclear, the judging part judges whether the cause is in the imaging device based on the detection information in a predetermined time period until the state occurs.

  • Patent number: 11348369
    Abstract: In an implementation, one or more user interactions from a virtual reality (VR) device user for initiating a service in a VR scenario of a VR application are detected. One or more eye physiological characteristics of the VR device user are obtained for user identity authentication. The obtained one or more eye physiological characteristics are compared with one or more pre-stored eye physiological characteristics samples. The VR device user is authenticated if the one or more eye physiological characteristics match at least a portion of the one or more pre-stored eye physiological characteristics samples, and a server that provides and performs the service is communicated with.

  • Patent number: 11335119
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for red eye detection are provided. In one aspect, a system includes an image acquisition device, first and second illuminators, and at least one processor. The first illuminator is arranged closer to the image acquisition device than the second illuminator. The image acquisition device is configured to capture a first facial image of a face of a subject with the first illuminator being on and the second illuminator being off and a second facial image of the face of the subject with the second illuminator being on and the first illuminator being off. The processor can process the first facial image based on the second facial image to determine whether at least one eye of the subject is live by determining that the first facial image includes a red eye reflection from the at least one eye.

  • Patent number: 11328043
    Abstract: Technology described herein can be embodied in a method for preventing access to a secure system based on determining a captured image to be of an alternative representation of a live person. The method includes capturing a first image and a second image of a subject illuminated by electromagnetic radiation in a first and a second wavelength ranges, respectively. The method also includes extracting, from the first image, a first portion representative of a sclera region of the subject, and from the second image, a second portion representative of the same region. It is determined that each of the first portion and the second portion includes features representative of vasculature in the sclera region, and in response, the subject in the image is identified to be an alternative representation of a live person. Upon search identification, the method includes preventing access to the secure system.

  • Patent number: 11314966
    Abstract: Embodiments of the invention are directed to a system and methods for determining a likelihood that an image that includes a user is a spoof or fake. In some embodiments, focus values are determined for various parts of the image during a focus sweep. The focus values may represent a focus point at which a particular part of the image is sharp. In some embodiments, the focus values may be determined only for the sections of the image that correspond to a face within the image. From the focus values, the system may determine a relative depth of various parts of the image. Using the relative depths, the system may generate a rough depth map for the image. The depth map may be analyzed to determine a likelihood that the image is authentic.

  • Patent number: 11308339
    Abstract: Biological organs and tissues can be identified using imaging or other data representing the organs and tissues. Example imaging modalities include 3D x-rays (including CT scans), MRI imaging, and millimeter wavelength scanning commonly used for airport security. Biomarkers may be identified as part of daily activities, such as airport travel, applying for government identifications (licenses and passports), medical appointments, and fitness monitoring. These imaging approaches may create static and dynamic data sets for comparison against existing data sets in a database. Biomarkers may identify (and predict) normal, morphological or morbidity changes over time. Such imaging biomarkers may securely identify individuals at critical checkpoints such as airports and border crossings. This approach is also applicable to plant identification and can provide a secure chain of custody for virtually any object.

    Abstract: A method for altering an eye color of a patient with a color alteration procedure is disclosed that may include imaging the iris with an image sensor prior to the color alteration procedure to generate an image of the iris. A mapping of the iris may be generated from the image. The mapping may include a number of regions corresponding to varying absorption coefficients of a treatment wavelength in the stromal pigment of the iris. A laser system may be set, based on the mapping, to deliver laser light at a laser power sufficient to cause elimination of at least a portion of stromal pigment in the iris. The laser light may then be delivered with the laser system.
