摘要： A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.

摘要翻译： 提供了一种编码运动图像的方法，其减少了块伪影。 该方法可以包括定义以块边界为中心的多个定义像素S 1，S 1 1和S 2 2。 如果选择了默认模式，则获得块边界周围的频率信息。 基于从完全在与块边界相邻的块内包含的像素中选择的对应的不连续分量的大小来调整属于块边界的频域中的不连续分量的大小。 然后将频域调整应用于空间域。 或者，可以选择DC偏移模式以减少在少量运动的平滑区域中的块伪影。
