Abstract
A method of utilizing an N-point primary transform core matrix to encode may include determining whether to use a first transform core matrix that is an N-point 8-bit primary transform core matrix. When a result of the determination is to use the first transform core matrix, the method may include: (i) constructing the first transform core based on a set of unique numbers, and (ii) encoding using the derived primary transform core. The method may further include, when a result of the determination is to not use the first primary transform: (i) deriving a second transform core based on the same set of unique numbers, and (ii) encoding using the derived second transform core.
