ABSTRACT:
A method for determining a value for a missing target pixel in an image frame includes generating a classification index from a plurality of classification pixels in a classification window associated with the missing target pixel where the classification index indicates whether a recognizable pattern is detected in the classification window, using the classification index to select a filter index via a lookup table associated with the classification index, using the selected filter index to select a set of filter coefficients via a lookup table associated with the filter index, and calculating the value for the missing target pixel using the selected set of filter coefficients.
