Abstract:
A method and apparatus for encoding an image, and a method and apparatus for decoding an image are provided. In the image encoding method, an input image may be encoded hierarchically based on a unified image compression format, irrespective of whether the input image corresponds to a two-dimensional (2D) image, a stereo image, or a three-dimensional (3D) image. An encoded bit stream generated through the encoding may be transmitted to the image decoding apparatus.
Abstract:
A view transformer of an image processing apparatus may generate a first view transformation image by transforming a first view color image with a first resolution to a third view, and may generate a second view transformation image by transforming, to the third view, a second view color image with a second resolution higher than the first resolution. A parameter calculator of the image processing apparatus may calculate a per-pixel weight parameter that is applied to each of the first view transformation image and the second view transformation image. An image generator of the image processing apparatus may generate a third view color image corresponding to the third view by applying the calculated per-pixel weight parameter to the first view transformation image and the second view transformation image.
