Claim 14:
15. A non-transitory computer-readable medium storing program code, the program code comprising one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
apply an interpolation filter to a video sequence,
obtain a difference between maximum and minimum values of a plurality of neighboring samples of a first one among a luma block and related to the video sequence;
divide the obtained absolute difference into intervals;
perform quantization of the obtained absolute difference;
obtain a floor value based on the difference of which the quantization is performed;
obtain a derived value by using at least the difference and the intervals based on a look-up table; and
predict a sample of a different one among a chroma block related to the video sequence, based on the derived value.
