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.

Abstract: Provided is method and apparatus of compressing and restoring an image using filter information. The image compression apparatus may generate a reduced image by sampling an input image, determine filter information based on the input image and a decoded reduced image, and code the filter information and the decoded reduced image. Accordingly, a deterioration in an image quality may be prevented in transmitting the image using a limited bandwidth.
