Design of a Fast JND Algorithm Based on Discrete Wavelet Transform and its VLSI Implementation. Article Preview. Abstract: The computation of JND is very complex, which makes it difficult to embed it into integrated circuits. To solve this problem, Haar-DWT based JND model is exploited and its corresponding pipeline architecture is developed in This brief presents a novel very large-scale integration (VLSI) architecture for discrete wavelet packet transform (DWPT). By exploiting the in-place nature of the DWPT algorithm, this architecture has an efficient pipeline structure to implement high-throughput processing without any on-chip memory/first-in first out access. A folded architecture for lifting-based wavelet filters is proposed
