Lifting scheme - Wikipedia The generalized lifting scheme is a derivative of the lifting scheme, in which the addition and subtraction operations are absorbed into the update and prediction steps, respectively. These steps can be any (invertible) mapping, leading to a more general lifting scheme. Applications. Wavelet transforms that map integers to integers Wavelet transform - Wikipedia In mathematics, a wavelet series is a representation of a square-integrable (real- or complex-valued) function by a certain orthonormal series generated by a wavelet. This article provides a formal, mathematical definition of an orthonormal wavelet and of the integral wavelet transform. Matlab code for Integer Wavelet transform - YouTube

WAVELET TRANSFORMS THAT MAP INTEGERS TO INTEGERS A. R. CALDERBANK, INGRID DAUBECHIES, WIM SWELDENS, AND BOON-LOCK YEO August 1996 Abstract. Invertible wavelet transforms that map integers to integers have important appli-cations in lossless coding. In this paper we present two approaches to build integer to integer wavelet transforms.

The image steganography systems use either the spatial domain or the frequency domain to hide the secret information. The proposed technique uses spatial domain technique to hide secret information in the frequency domain. The cover image is transformed using integer wavelet transform to obtain four subbands: LL, LH, HL, and HH. Design and Evaluation of Integer Dual Tree Complex Wavelet ...

In this paper, integer Dual Tree Complex Wavelet Transform (DTCWT) filters are derived from basic DTCWT filters A data hiding scheme based on multidirectional line ...

The Integer Wavelet Transform is the major component in the JPEG 2000 based dynamic region of interest coding scheme. The wavelet transform helps to concentrate the signal energy to fewer coefficients to increase the degree of compression when the data is encoded.

INTEGER WAVELET TRANSFORM The wavelet transform is a very useful technique for image analysis, and Lifting Wavelet Transform is an advance form of wavelet transform which allows easy computation, better reconstruction of original image and close approximation of some data sets.
