A system processes an image containing a first line and a second line, where the first and second lines includes a plurality of pixels, to generate an interpolated line. The system selects a first and second set of pixels from the first line and second line, respectively, and generates a first set and second set of filtered values by filtering the first set and second set of pixels with a first and second filter, respectively. The system identifies in the first line an edge location in the first set of the filtered values by a first filtered value of the first set of filtered values being at least one of less than and equal to a first predetermined value and a second filtered value of the first set of the filtered values being at least one of greater than and equal to the first predetermined value. The system also identifies in the second line an edge location in the second set of filtered values by a first filtered value of the second set of the filtered values being at least one of less than and equal to a second predetermined value and a second filtered value of the second set of filtered values being at least one of greater than and equal to the second predetermined value. The system then interpolates based on the edge location of the first line and the edge location of the second line to generate an interpolated pixel of the interpolated line.
