Abstract : Due to the importance of the 2-D biorthogonal wavelet transforms in image and video processing applications, this paper reports on the design and hardware implementation of an efficient architecture for the non-separable 2-D discrete biorthogonal wavelet transforms. The architecture adopts symmetrical extension at the image boundaries, therefore it conforms the JPEG-2000 standard. It computes the DBWT decomposition of an NxN image in approximately 3N2/2 clock cycles (ccs). Hardware implementation results based on a Xilinx Virtex-2000E FPGA chip are also provided.
