IT IS AN CODING FOR DWT IN VHDL

In this paper we propose a watermarking system that uses the biorthogonal discrete wavelet transform, DWT and the message is encoded before embedding. The proposed watermarking method is very simple, implying four steps: turbo coding of

a new hybrid transform coding methodology for lossy image compression that integrates discrete wavelet transform, discrete cosine Transform and singular value decomposition methods is proposed. The proposed system has enhancements in both the com
