    Abstract: An adaptive Wiener filter may be applied to improve coding efficiency because of information lost during quantization of the video encoding process. The Wiener filter may be selectively applied globally to an entire picture or locally to portions of the picture. Histogram segmentation may be used to select pixels for Wiener filtering in some embodiments. The Wiener filter may be adaptively applied to histogram bins, improving coding efficiency in some cases.

    Abstract translation: 可以应用自适应维纳滤波器来提高编码效率,因为在视频编码处理的量化期间信息丢失。 Wiener滤波器可以全局地选择性地应用于整个图像,或者局部地应用于图像的一部分。 在一些实施例中,直方图分割可用于选择维纳滤波的像素。 维纳滤波器可以自适应地应用于直方图盒,在一些情况下提高编码效率。
