Abstract: The format of telecined video may be determined including a bottom field first cadence. In addition, video using 2:3:3:2 top field first can be identified. Moreover, mixed cadence videos can also be detected. In some embodiments, mixed cadence videos may be detected by calculating variances of different areas within a frame.

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: A video encoder may use an adaptive Wiener filter inside the core video encoding loop to improve coding efficiency. In one embodiment, the Wiener filter may be on the input to a motion estimation unit and, in another embodiment, it may be on the output of a motion compensation unit. The taps for the Wiener filter may be determined based on characteristics of at least a region of pixel intensities within a picture. Thus, the filtering may be adaptive in that it varies based on the type of video being processed.
Abstract translation: 视频编码器可以在核心视频编码环路内使用自适应维纳滤波器来提高编码效率。 在一个实施例中,维纳滤波器可以在运动估计单元的输入上,并且在另一个实施例中,其可以在运动补偿单元的输出上。 用于维纳滤波器的抽头可以基于图像内的像素强度的至少一个区域的特性来确定。 因此,滤波可以是适应性的,因为它根据正在处理的视频的类型而变化。
