System and method for adjacent field comparison in video processing

A method for processing video information, the method comprising:

• performing by one or more processors, one or more circuits, or any combination thereof integrated within a single chip:
• calculating a first two-field difference between a first plurality of pixels from a current field and a second plurality of corresponding pixels from a first alternate field adjacent to said current field;
• calculating a second two-field difference between said first plurality of pixels from said current field and a third plurality of corresponding pixels from a second alternate field adjacent to said current field;
• filtering said first two-field difference to obtain a first weighted filtered result;
• filtering said second two-field difference to obtain a second weighted filtered result;
• and
• removing artifacts by deinterlacing at least one pixel from said current field based at least in part on said calculated first weighted filtered result and said calculated second weighted filtered result.

A system for processing video information, the system comprising:

• at least one processor that enables calculation of 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 said current field;
• said at least one processor enables filtering of said first two-field difference to obtain a first weighted filtered result;
• and
• said at least one processor enables removing artifacts by deinterlacing, using one or more of a plurality of deinterlacing methods, at least one pixel from said current field, said one or more of a plurality of deinterlacing methods selected based at least in part on said calculated first weighted filtered result.
