(57) ABSTRACT A depth-sensing method for a time-of-flight depth camera includes
irradiating a subject with pulsed light of spatially alternating bright and dark features, and …

A portable, hand held iris imaging system captures iris images that may be used in biometric
identification. The system is constructed using two separate but coupled subsystems. A first …

An improved solution for generating depth maps using time-of-flight measurements is
described, more specifically a time-of-flight imager and a time-of-flight imaging method with …

Iris recognition used the iris features to verify and identify the identity of human. The iris has
many advantages such as stability over time, easy to use and high recognition accuracy …

A portable, hand held iris imaging system captures iris images that may be used in biometric
identification. The system includes an illumination source for illuminating a subject's eye and …

The invention provides a method for iris based biometric recognition. The method includes
receiving an image from an image sensor and determining whether the received image …

BACKGROUND The present invention relates to autofocus optical systems, and more
particularly to estimation of error in images received through an optical system. An autofocus …
