Abstract: Improved mechanisms for three-dimensional image reconstruction are disclosed. A user is presented with a scene image and allowed to select elements of the image, such as planes, within which features are to be detected. The features are detected and tracked and objects (such as planes) are constructed. The user is allowed to revise the constructed objects and may be allowed to repeat image element selection, with feature detection and tracking and object construction being repeated. When element selection and object construction and user revision are completed, a three-dimensional reconstruction of the scene image is computed.

Abstract: A method, apparatus and computer program product are provided for iris recognition using natural light. A method is provided for receiving, at a user device, a plurality of iris images. The iris images are captured using natural light. The method also includes generating a composite iris ring based on the plurality of iris images, receiving an iris pattern, comparing the composite iris ring to the iris pattern, and determining a match probability based on the comparison of the composite iris ring to the iris pattern.
