An Incorporated DWT Block-based Watermarking Algorithm with JND
Liu Juan-mei · Computer and Modernization · 2008
This paper proposes a new approach.The new approach incorporates a DWT block-based algorithm with JND.It makes use of contrast sensitivity and masking in HVS to classify the blocks,then embed watermark with different weighted coefficient.The experiment shows that the watermarks generated with the proposed algorithm are invisible and robust against commonly used image processing techniques.
