1. A method comprising:
determining filter coefficients for a two-dimensional (2D) finite impulse response (FIR) filter;
applying the 2D FIR filter using the determined filter coefficients to a first pixel p(x,y) at a first virtual boundary of a reconstructed coding unit, wherein x is a coordinate on an x-axis of the reconstructed coding unit and y is a coordinate on a y-axis of the reconstructed coding unit;
computing a first filtered pixel value based on the filtered first pixel p(x,y) and replicated values in which a replicated value for a pixel p(x−1,y−1) is replicated from a value of a pixel p(x−1,y); and
outputting the first filtered pixel value.
