  • Publication number: 20160019420
    Abstract: Certain aspects relate to systems and techniques for generating high resolution iris templates and for detecting spoofs, enabling more reliable and secure iris authentication. Pairs of RGB and NIR images can be captured by the iris authentication system for use in iris authentication, for example using an NIR LED flash and a four-channel image sensor. Multiple images of the user's iris can be captured by the system in a relatively short period of time and can be fused together to generate a high resolution iris image that can contain more detail of the iris structure and unique pattern than each individual images. The “liveness” of the iris, referring to whether the iris is a real human iris or an iris imitation, can be assessed via a liveness ratio based on comparison of known iris and sclera reflectance properties at various wavelengths to determined sensor responses at those same wavelengths.

  • Patent number: 9171355
    Abstract: Systems and methods for multispectral imaging are disclosed. The multispectral imaging system can include a near infrared (NIR) imaging sensor and a visible imaging sensor. The disclosed systems and methods can be implemented to de-noise a visible light image using a gradient scale map generated from gradient vectors in the visible light image and a NIR image. The gradient scale map may be used to determine the amount of de-noising guidance applied from the NIR image to the visible light image on a pixel-by-pixel basis.

  • Publication number: 20140146205
    Abstract: Described herein is a system and method for adjusting the orientation of captured video utilizing the data received from a built-in inertial measurement unit such as an accelerometer. During video capture, the device may be held in a position that is not fully vertical or horizontal, and thus not match the true orientation of a scene. This can cause the captured video to appear rotated during playback at the same angle of rotation as the video capture device. The described system can adjust the playback orientation of the rotated video by utilizing sensor data captured during the same time as the video was captured.
