1. A method for deinterlacing a video frame comprising the steps of:
- a. obtaining a video frame;
b. identifying an edge within said frame;
c. selecting a first pixel within said edge;
d. computing a plurality of non-negative threshold values by applying at least one function to a plurality of pixels proximate to said first pixel;
e. selecting a plurality of second pixel values based upon said computation of non-negative threshold values; and
f. applying a filter function to said selected plurality of second pixel values.

Abstract
The present invention is directed to systems and methods for deinterlacing a video frame by obtaining a video frame, identifying an edge within the frame, selecting a first pixel within the edge, computing a plurality of non-negative threshold values by applying at least one function to a plurality of pixels proximate to the first pixel, obtaining a plurality of second pixel values based upon the computation of non-negative threshold values, and applying a filter function to the selected plurality of second pixel values.

15. A method for deinterlacing a video frame comprising the steps of:
-
a. obtaining a video frame; b. identifying an input edge having an angle and a step height within said frame; c. applying a plurality of functions to pixels within said input edge to generate an output edge wherein, for said input edge having an angle in the range of 90 degrees to 20 degrees and −
90 degrees to −
20 degrees and a step height equal to N, the corresponding output edge has a step height equal to N and wherein, for said input edge having an angle in the range of 20 degrees to about 1 degree and about −
1 to −
20 degrees and a step height equal to N, the corresponding output edge has a step height equal to N+1. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
