According to the reviewer's comments, we updated the last paragraph of Section 1 as follows: We replaced “Section 2 presents a proposed inverse transform using linearity to reduce the computational complexity.” With “In Section 2.1, we introduce the transforms used in VVC. And we propose a fast inverse transform using linearity to reduce the computational complexity in Section 2.2.” Comment) Methodology Section: It should be structured, sub-headings should be added to facilitate tracking and understanding.
