摘要： A method, medium, and system encoding and/or decoding a moving picture. The moving picture encoding method may include selecting a prediction mode that is optimal for the macro blocks, which correspond to each other, of the color components of a current image based on the characteristics of a predetermined image, generating a predicted image for the current image according to the selected prediction mode, and encoding a moving picture using the predicted image. An optimal prediction mode can be adaptively applied to the macro blocks, which correspond to each other, of the color components, thereby increasing the moving picture's encoding and decoding efficiencies.

摘要： A residue image down- and/or up-sampling method and apparatus and an image encoding and/or decoding method and apparatus using the residue image down- and/or up-sampling method and apparatus are provided. The residue image downsampling method includes: generating a residue corresponding to the difference between an original image and a predicted image, for each image component of the original image formed with at least two or more image components; and downsampling the residue for each image component at a predetermined ratio. The residue image upsampling method includes: upsampling data downsampled from residue data of an original image; and restoring the original image by adding the predicted image to the upsampled residue of each component. According to the methods and apparatuses, a residue image is obtained by performing spatiotemporal prediction encoding first, and by sampling this residue image, loss of information occurring in the sampling process can be reduced. Since sampling is performed with a residue image obtained through a spatiotemporal prediction process, even when an original image that is not color transformed is directly encoded, sampling can be performed effectively. Also, the methods and apparatuses have an advantage that in addition to colors, sampling of any components can be performed effectively.
摘要翻译：提供了残留图像下采样和/或上采样方法和装置以及使用残留图像下采样和/或向上采样方法和装置的图像编码和/或解码方法和装置。残留图像下采样方法包括：对于具有至少两个或更多个图像分量形成的原始图像的每个图像分量，产生对应于原始图像和预测图像之间的差的残差; 并以预定比例对每个图像分量进行下采样。残差图像上采样方法包括：从原始图像的残差数据向下采样数据; 并且通过将预测图像添加到每个分量的上采样残差来恢复原始图像。根据方法和装置，首先通过执行时空预测编码获得残差图像，并且通过对该残差图像进行采样，可以减少在采样处理中发生的信息的丢失。由于采用通过时空预测处理获得的残差图像进行采样，所以即使直接编码未被颜色变换的原始图像，也可以有效地进行采样。此外，该方法和装置具有除了颜色之外还可以有效地执行任何部件的采样的优点。

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： An encoding method may comprise obtaining a residue corresponding to a difference between the original image and a prediction image with respect to each component of the original image, encoding the residue of a predetermined component of the original image, restoring the encoded residue of the predetermined component and transforming the restored residue into a predetermined value including the restored residue value, and encoding prediction residues corresponding to differences between each of residues of components of the original image, which are not encoded, and the residue, which is restored and transformed into the predetermined value. Since prediction residues are encoded and decoded using correlations between residues of image components and image components, data amount is highly reduced. Also, since there is no quality loss in a picture generated by directly encoding an R-G-B image without transforming it into a Y-Cr-Cb image, high quality image information is obtained.
摘要翻译：编码方法可以包括对原始图像和原始图像的每个分量之间的原始图像和预测图像之间的差异相对应的残差，对原始图像的预定分量的残差进行编码，恢复预定分量的编码残差将恢复的残留变换为包括恢复的残差值的预定值，以及编码对应于未被编码的原始图像的分量残差中的每个残差之间的差异的预测残差和被恢复并变换为预定的残差的残差值。由于使用图像分量和图像分量的残差之间的相关性对预测残差进行编码和解码，所以数据量大大降低。此外，由于通过直接编码R-G-B图像而不将其变换为Y-Cr-Cb图像而产生的图像中没有质量损失，因此获得高质量的图像信息。
