    摘要: An encoding method, medium, and system encoding an image, with an image being encoded by generating a plurality of image slices as images of each color component of the image and encoding the image slices in parallel with each other and independently of each other. Accordingly, although an image to be encoded has a large number of color components, the image can be compressed promptly. In addition, a decoding method, medium, and system are also provided decoding an image, with a plurality of encoded image slices being included in a corresponding bitstream, which are images of each color component of the image to be restored, are decoded in parallel with each other and independently of each other so as to restore the image using the decoded image slices. Accordingly, although an image to be decoded has a large number of color components, the image can be restored promptly.

    摘要: A video encoding/decoding apparatus and method for color images include a first motion prediction unit that generates a first prediction residue image of an input image on a basis of a first motion prediction result of the input image. An image information detection unit sets a predetermined color component of an R-G-B image to a reference color component and determines whether the input image is a Y-Cb-Cr image or an R-G-B image and whether a color component is the reference color component. A second motion prediction unit performs motion prediction for the first prediction residue image and generates a second prediction residue image if the input image is the R-G-B image and the color component of the input image is not the reference color component.

    摘要: Provided are a method and apparatus for encoding/decoding a moving picture by using the diffusion properties of the image. In the method, a value of a current pixel is predicted from the values of neighboring pixels of the current pixel, based on the variations between the values of the neighboring pixels present in directions toward the current pixel; a correction value of the predicted value is calculated from at least one variation from among the variations; the value of the current pixel is determined by reflecting the correction value into the predicted value; and then, the original image is reconstructed using the determined value of the current pixel.
