A method and system for uniquely identifying a subject based on an iris image. After obtaining the iris image, the method produces a filtered iris image by applying filters to the iris image to enhance discriminative features of the iris image. The method analyzes an intensity value for pixels in the filtered iris image to produce an iris code that uniquely identifies the subject. The method also creates a segmented iris image by detecting an inner and outer boundary for an iris region in the iris image, and remapping pixels in the iris region, represented in a Cartesian coordinate system, to pixels in the segmented iris image, represented in a log-polar coordinate system, by employing a logarithm representation process. The method also creates a one-dimensional iris string from the iris image by unfolding the iris region by employing a spiral sampling method to obtain sample pixels in the iris region, wherein the sample pixels are the one-dimensional iris string.

Computationally efficient feature extraction and matching iris recognition

In one example embodiment, a system includes a content provider configured to transmit video content including a plurality of scenes; and an apparatus configured to: receive an input including a target playing time of the video content and a condition for changing a playing speed, determine a priority value for each of the scenes based at least in part on the condition for changing the playing speed, and determine a playing speed of each of the scenes based at least in part on the determined priority value and the target playing time of the video content.

Control video content play speed

An image display apparatus and a method for operating the same are disclosed. The method for operating an image display apparatus includes receiving an image including at least one three-dimensional (3D) object, calculating a depth value of the at least one 3D object, changing at least one of sharpness and brightness of pixels corresponding to the at least one 3D object according to the depth value and generating an output image including the changed at least one 3D object, and displaying the output image.
