Claim 9:
10. The computing device of claim 9, wherein the one or more processors configured to control the internal bit-widths of the PROF derivation process for various representation precisions of internal the PROF parameters by applying right-shifting to the internal PROF parameters are further configured to:
obtain a horizontal gradient value of a first prediction sample I(i,j) based on a difference between a first prediction sample I(i+1,j) and a first prediction sample I(i−1,j);
obtain a vertical gradient value of the first prediction sample I(i,j) based on a difference between a first prediction sample I(i,j+1) and a first prediction sample I(i,j−1);
right shift the horizontal gradient values by a first bit-shift value; and
right shift the vertical gradient values by the first bit-shift value.
