1. A method for determining a value for a missing target pixel in an image frame, the method comprising:
(a) generating a classification index from a plurality of classification pixels in a classification window associated with the missing target pixel, wherein the classification index indicates whether a recognizable pattern is detected in the classification window;
(b) utilizing the classification index to select a filter index from a plurality of filter indexes via a lookup table associated with the classification index;
(c) utilizing the selected filter index to select a set of filter coefficients from a plurality of sets via a lookup table associated with the filter index; and
(d) calculating the value for the missing target pixel using the selected set of filter coefficients.
