Abstract: An image processing method for demosaicing with reduced moire includes selecting, with respect to a target channel among a plurality of color channels for an input image, a target pixel unassigned with a color value for the target channel, calculating, with respect to the target pixel, gradient values respectively corresponding to a first direction and a second direction associated with the target channel, calculating, with respect to the target pixel, moire values respectively corresponding to the first direction and the second direction, and determining an interpolation direction of the target pixel for the target channel to be one of the first direction and the second direction, based on the calculated gradient values and the calculated moire values.

Abstract: A method and apparatus for outputting a three-dimensional (3D) image are provided. To output a 3D image, a stereo image is generated based on viewpoints of a user and rendered into a 3D image. Since the stereo image is generated based on the viewpoints of the user, the user views a different side of an object appearing in the 3D image depending on a viewpoint of the user.

Abstract: A calibration method for a three-dimensional (3D) augmented reality and an apparatus thereof are provided. The calibration method includes determining a first conversion parameter representing a relationship between a coordinate system of an eye-tracking camera and a coordinate system of a calibration camera by capturing a physical pattern using the eye-tracking camera and the calibration camera, and determining a second conversion parameter representing a relationship between a coordinate system of a virtual screen and the coordinate system of the calibration camera and a size parameter representing a size of the virtual screen by capturing a virtual pattern displayed on the virtual screen using the calibration camera.
