ABSTRACT:
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.
