VLSI Design and Implementation of Embedded Zerotree Wavelet Image CODEC with Digital Watermarking

The paper proposes that Embedded Zreotree Wavelet
algorithm and the architecture of the modified
EZW algorithm will have the property of regularity,
modularity ,and scalablity, and also posses the
function , which can allow a detected watermark
to be embedded. The methods to realize the
algorithm and the function of watermark are to
analyze the theory of algorithm and the order
of output and input data and then to use queue
and stack, the unit of memory, and the control
of circuit.
The modified EZW architecture needs a half less
memory units than the original one, and functions
nearly as effective as the original architecture.
Besides, this paper points out that the whole
architecture of the transform CODEC system can
be applied properly to HDTV, MPEG-4 system, or
QoS network.
