| Abstract(in English) | This paper presents an IntDCT with only dyadic values such as k/2^n (k, n∈N). Although some IntDCTs have been proposed, they are unsuitable for lossless-to-lossy image coding in allocation of low bit word length to lifting coefficients. First, the proposed M-channel integer WHT (IntWHT) can be constructed by only (log_2 M)-bit word length coefficients and has structural regularity. Then, our 8-channel IntDCT keeps good coding performance even in low-bit word length because IntWHT, which is main part of IntDCT, can be implemented by 3-bit word length. Finally, our method is validated in lossless-to-lossy image coding. |
