According to reviewer’s comment, we the following sentences at the end of the Introduction. “In this paper, we analyze the number of multiplications of the existing fast transform methods in the VVC standard, and we propose a new fast inverse transform using the number of non-zero coefficients based on linearity to reduce the number of multiplications.” Comment 2) Discussion Section: The authors did not respond accurately to this comment.
The results show a higher performance of the proposed computation of inverse transforms.
