Hyperspectral image coding based on three-dimensional integer wavelet transform;

Lossless compression based on integer wavelet transform for MODIS multispectral images;

A semi-blind fragile watermarking algorithm based on integer wavelet transform;

Experiment results show that the fusion method based on complex wavelet transform is remarkably better than that based on classical discrete wavelet transform.

As a newly developed multiresolution method,the complex wavelet transform provides approximately shift-invariant and directionally-selective filters.

Generalized Gaussian distribution statistic model is constructed by taking advantage of the statistical attribution of complex wavelet transformation coefficients.

The largest Lyapunov exponent of a discrete dynamical system can be obtained by calculating the largest Lyapunov exponent of the small-scale wavelet transform modulus of the discrete dynamical system.

The core idea is analyzing the pending data to obtain the optimal approximate length,hence optimize the boundary treatment,while analyzing the optimal approximate length to select the wavelet transform bases adaptively.

A fragile watermark is designed using integral wavelet transform combined with hash function in order to verify the integrity of medical images.

This paper presents a fragile watermarking scheme based on integral wavelet transform.

So I put up the analysis of the basic theory and some usual methods with the image compression,and I went along two kinds of the technology about lossless compression coding for the image, one is image extraction sampling technology, another is image coding technology based on the integral wavelet transform.
