    • Disclosed herein is a method for selectively filtering and encoding a video signal having at least one frame including a matrix of pixels. The method includes selecting a set of pixels within the frame, determining an initial performance measurement for the selected set of pixels, provisionally applying each filter to the set of pixels, determining a second performance measurement for each filter provisionally applied to the selected set of pixels, and applying the at least one filter to the selected set of pixels to generate a reconstruction of the frame if the at least one filter is determined to have a second performance measurement that is better than the initial performance measurement.
    • 这里公开了一种用于选择性地过滤和编码具有包括像素矩阵的至少一个帧的视频信号的方法。 该方法包括选择帧内的一组像素,确定所选择的像素组的初始性能测量,将每个滤波器临时应用于像素组,确定临时应用于所选择的像素集合的每个滤波器的第二性能测量 以及如果确定所述至少一个滤波器具有比初始性能测量更好的第二性能测量,则将所述至少一个滤波器应用于所选择的像素集合以产生所述帧的重构。

    • A method for encoding and decoding a video signal having frames with blocks comprised of pixels. The method reduces the complexity of the video signal to be encoded by applying a filter scheme to the input data stream in an encoder and later reversing the filter scheme in a decoder. A number of filter schemes may be tested to determine the best filter scheme that most reduces the number of distinct color values per color plane. The best filter scheme is used to filter the data to be encoded. Filter information of the best filter scheme is included in the encoded data to enable the decoder to identify the best filter scheme in order to apply the best filter scheme in reverse to re-create the original data stream.
    • 一种用于对具有由像素组成的块的帧的视频信号进行编码和解码的方法。 该方法通过将滤波器方案应用于编码器中的输入数据流并且稍后在解码器中反转滤波器方案来降低要编码的视频信号的复杂度。 可以测试多个滤波器方案来确定最佳滤波器方案,其最大程度地减少每个颜色平面的不同颜色值的数量。 最佳滤波器方案用于过滤要编码的数据。 编码数据中包含最佳滤波器方案的滤波器信息,以使解码器能够识别最佳滤波器方案,以便相反地应用最佳滤波器方案来重新创建原始数据流。
