摘要：

Contrary to one of the key conclusions of the above paper,(1) the cross-correlation of the 1-D SA-DCT coefficients located in two columns of different sizes does not necessarily take maximum values at the same indices, The correct way to measure the cross-correlation of the SA-DCT coefficients after the first stage of the transform is presented in this letter, The idea of implementing shape-adaptive DCT and some aspects of their work could nevertheless be useful.
