Application of Biothogonal Wavelet in Facial Feature Extraction;

The paper shows that biothogonal wavelet transform coefficients,modified by non-linear operators,can reconstruct Mammography and make more obvious barely seen feature (mass)of mammography in order to detect breast cancer more early and accuratel y.

篒n this paper, an image compression encoding method based on biothogonal wavelet transformationis presented.

Lifting scheme design of biorthogonal wavelet for aviation image compression;

Construction of 7/5 biorthogonal wavelet and its application to image coding;

Research of subpixel subdivision location algorithm for star image based on biorthogonal wavelet;

Optimized biorthogonal wavelets design method for image compression;

And a program for constructing biorthogonal wavelets has been given.

For the various needs, a novel algorithm that is used to lift the vanishing moments of wavelet from arbitrary biorthogonal wavelets, and not only from Lazy wavelet, is proposed.

In this paper we study the bi-orthogonal wavelet in the rectangular domain and compress segmentation image use the bi-orthogonal wavelet.

A new method is proposed that the real and imaginary parts of the analy\ic signals of the echoes are transformed with linear phase bi-orthogonal wavelet respectively,and then the modular values of the wavele.

In this dissertation, image compression method and improved method based on bi-orthogonal wavelet packet was discussed in detail.
