Description: 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 of the image. Our proposed watermarking algorithm
embeds the watermark into the tetrolet coefficients which are
selected by considering different of shapes tetrominoes. We
uated the effectiveness of the watermarking approach by
considering the quality metrics like RMSE, PSNR and
Robustness parameters. The experimental results reveal that the
proposed watermarking scheme is robust against common image
processing attacks.

Description: This Program presents discrete wavelet transform (DWT) and its inverse (IDWT) with Haar wavelets as tools to compute the variable size interpolated versions of an image at optimum computational load. As a human observer moves closer to or farther a scene, the retinal image of the scene zooms in or out, respectively. This zooming in or out can be modeled using variable scale interpolation. -This Program presents discrete wavelet transform (DWT) and its inverse (IDWT) with Haar wavelets as tools to compute the variable size interpolated versions of an image at optimum computational load.
