1. A method of coding video data, the method comprising:
deriving, based on neighbor samples, filter parameters for a second filter, wherein the neighbor samples comprise neighbor samples of a current block of the video data or neighbor samples of a reference block of the video data and wherein the second filter comprises one or more of a bilateral filter (BIF) or a Hadamard Domain Transform Filter (HTDF);
generating predicted samples by applying, in a predicted samples domain, a first filter, the first filter comprising an interpolation filter, and the second filter to samples of the current block, the second filter corresponding to the filter parameters;
generating one or more of:
residual data based on the predicted samples, or
reconstructed samples based on the predicted samples; and
coding the video data based on one or more of the residual data or the reconstructed samples.
