Simplified bilateral intra smoothing filter

Abstract

A method comprises receiving a plurality of reference pixels, computing a plurality of filter coefficients based on differences between a reference pixel and neighboring reference pixels in the plurality of reference pixels, and combining the filter coefficients with the reference pixel and the neighboring reference pixels to generate a filtered value, wherein the filtered value is used for intra prediction.
