    • An encoding method includes selecting a run detection method in accordance with characteristics of image data, generating a run value by detecting a run that is repeated in the image data in accordance with the selected run detection method, generating run count bits by counting the number of repetitions of the detected run, and performing a run-length encoding using the detected run values and the run count bits. The run detection method includes a coefficient run detection method that detects a run based on pixel values, a pattern run detection method that detects the run based on whether the pixel blocks have a specified pattern, a difference run detection method that detects the run based on a difference value between two successive pixel values, and a residual run detection method that detects the run based on an error value that is a difference value between an actual pixel value and a predicted value.
    • 一种编码方法,包括根据图像数据的特性来选择运行检测方法,通过根据所选择的运行检测方法检测在图像数据中重复的运行来生成运行值,通过对运行计数位的数量进行计数来生成运行计数位 重复检测到的运行,以及使用检测到的运行值和运行计数位来执行游程长度编码。 运行检测方法包括:基于像素值检测运行的系数运行检测方法,基于像素块是否具有指定图案来检测运行的图案运行检测方法;基于检测运行的差分运行检测方法,基于 两个连续像素值之间的差值,以及基于作为实际像素值和预测值之间的差值的误差值来检测运行的剩余运行检测方法。

    • A method and apparatus for generating video packets and a method and apparatus for restoring video are provided. The method of generating video packets includes: generating at least one pixel block consisting of at least one reference pixel and a plurality of neighboring pixels adjacent to the at least one reference pixel from pixels of a video frame; replacing pixel values of the neighboring pixels in the at least one pixel block with pixel difference values, which are difference values between a pixel value of one of pixels adjacent to the neighboring pixels and the pixel values of the neighboring pixels; generating packets so that a pixel value of the at least one reference pixel and the pixel difference values of the neighboring pixels are allocated to different packets according to positions of the pixels; and performing entropy coding of some of the packets including the pixel difference values of the neighboring pixels.
    • 提供了一种用于产生视频分组的方法和装置以及用于恢复视频的方法和装置。 产生视频分组的方法包括:从视频帧的像素生成由与至少一个参考像素相邻的至少一个参考像素和多个相邻像素组成的至少一个像素块; 用像素差值代替所述至少一个像素块中的相邻像素的像素值,所述像素差值是与相邻像素相邻的一个像素的像素值与相邻像素的像素值之间的差值; 生成分组,使得根据像素的位置将所述至少一个参考像素的像素值和相邻像素的像素差值分配给不同的分组; 并执行包括相邻像素的像素差值的一些分组的熵编码。
