Abstract
A method for performing a transform by using Layered Givens Transform may include: deriving at least one rotation layer, a first permutation layer and a second permutation layer based on a given transform matrix H and an error parameter; obtaining a Layered Givens Transform (LGT) coefficient based on the rotation layer, the first permutation layer and the second permutation layer; and performing quantization and entropy encoding with respect to the LGT coefficient, the first permutation layer and the second permutation layer may include a permutation matrix obtained by permuting a row of an identity matrix, and the LGT coefficient may be obtained by sequentially applying the first permutation layer, the rotation layer and the second permutation layer respectively.
