In this paper the analysis of the compression process was performed by comparing the compressed signal against the original signal. To do this the most powerful speech analysis and compression techniques such as Linear Predictive Coding (LPC) and Dis

This paper proposes new watermarking technique based on tetrolet domain. The tetrolet transform is a new adaptive Haar-type wavelet transform based on tetrominoes. It avoids Gibbs oscillation because it applies the Haar function at the edge o

Seam carving based on dynamic algorithm using to generate the minimal of seam carving and compressing with wavelet transform in DCT-DWT with high PSNR.
