摘要:
A method and apparatus for processing an image signal includes an image signal encoding apparatus and an image signal decoding apparatus that use an independent luminance and chrominance image signal to reduce a crosstalk. The independent luminance and chrominance image signal may include a luminance signal and a chrominance signal. The image signal encoding apparatus and the image decoding apparatus may perform down-sampling or up-sampling on the chrominance signal. The image signal encoding apparatus and the image decoding apparatus may increase a compression efficiency of the independent luminance and chrominance image signal, by applying different quantization parameters and different bit-depths to the luminance signal and the chrominance signal, respectively.
摘要:
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.
摘要:
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.

An apparatus and method for encoding and de1/5/2012coding motion information and disparity information are provided. The apparatus may extract a vector from peripheral blocks of a current block, which is a vector of the same type as a vector used for predicting and compensating the current block, and perform prediction and compensation of the current block using the extracted vector.
