8.6.2. Filtering

Depending on whether each pixel is tagged as a horizontal and/or vertical edge, 1 of 4 different 3×3 filter kernels is applied (and the result divided by 16) to produce the final output pixel.
Note: In edge-adaptive sharpen, the filter is fixed at 3×3 taps and all parameters regarding coefficient precision are ignored. There is also no option to override the coefficients used in the filter kernels.
