Claim 13:
14. A decoder of video data comprising circuitry, including a processor and memory, configured to:
decode a video block of the video data using a linear model of a template-based video coding technique, the decoding comprises:
determining minimum and maximum values of luma samples neighboring a coding block;
determining minimum and maximum values of chroma samples neighboring the coding block and corresponding to the chroma for the minimum and maximum values of the luma samples, respectively;
computing a first parameter of the linear model (i) as a function of a single look up table, including values for determining least significant bits only, and the minimum and maximum values of the chroma samples and (ii) at a first precision, wherein the first precision is less than or equal to 16 bits;
computing a second parameter of the linear model (i) as a function of the minimum value of the chroma samples, the minimum value of the luma samples and the first parameter of the linear model and (ii) at a second precision, wherein the second precision is less than or equal to 16 bits; and
predicting chroma samples of the coding block based on the first parameter, the second parameter and reconstructed luma samples of the coding block.
