    • Methods and systems for processing video information are disclosed herein and may comprise calculating a first two-field difference between a first plurality of pixels from a current field and a second plurality of corresponding pixels from an alternate field adjacent to the current field. At least one pixel from the current field may be deinterlaced based at least in part on the calculated first two-field difference. The first plurality of pixels and the second plurality of pixels may be aligned by adjusting a phase of at least one of the first plurality of pixels and the second plurality of pixels prior to the calculation of the first two-field difference. The first plurality of pixels may include a plurality of vertically adjacent pixels. The first plurality of pixels may comprise at least one luminance component. The alternate field may include a previous field and/or a next field. The first plurality of pixels and the second plurality of pixels may be filtered prior to the calculation of the first two-field difference.
    • 本文公开了用于处理视频信息的方法和系统,并且可以包括计算来自当前场的第一多个像素与来自与当前场相邻的替代场的第二多个对应像素之间的第一两场差。 至少一部分来自当前场的像素可以至少部分地基于所计算出的第一两场差异进行去隔行扫描。 通过在计算第一双场差之前调整第一多个像素和第二多个像素中的至少一个的相位来对齐第一多个像素和第二多个像素。 第一多个像素可以包括多个垂直相邻的像素。 第一多个像素可以包括至少一个亮度分量。 替代字段可以包括前一字段和/或下一字段。 可以在计算第一双场差之前对第一多个像素和第二多个像素进行滤波。

    • A method for processing video information may include calculating a polarity change count (PCC) for a plurality of pixel pairs selected from a plurality of pixels from different fields utilizing a plurality of difference polarity values associated with the plurality of pixel pairs. At least a portion of the plurality of pixels from different fields may be deinterlaced based on at least the calculated PCC. The plurality of difference polarity values may be calculated for the plurality of pixel pairs selected from the plurality of pixels from different fields. At least one difference in amplitude of at least one of the selected pixel pairs may be calculated for the calculating the plurality of difference polarity values. The plurality of pixels from different fields may comprise a plurality of adjacent pixels from a plurality of woven fields.
    • 用于处理视频信息的方法可以包括利用与多个像素对相关联的多个差异极性值,从不同场选择多个像素对,计算极性改变计数(PCC)。 至少基于所计算的PCC,来自不同场的多个像素的至少一部分可以被去隔行扫描。 可以针对从不同场选择的多个像素中选择的多个像素对来计算多个差异极性值。 可以计算至少一个所选像素对的振幅的至少一个差异,用于计算多个差极性值。 来自不同场的多个像素可以包括来自多个编织区域的多个相邻像素。
