Abstract:

Now, wavelet analysis has been applied on 2D image process. For
example, it has been applied on image press, edge detection and noise
filter et. . In 2D wavelet analysis , the construction of 2D mother
wavelet is important and difficult. Some scientists have make some
works. For example, Mallat raised product of tensor construction
method. Long Rui-Ling given direct construction method. Wickerhauser
made mutildimensional library trees, et. . They concern the mother
wavelet which can construct orthogonal basis. But, in fact, there are
some 1D mother wavelets which can not construct orthogonal basis.. For
example , 1D spline mother wavelets. These mother wavelets have been
applied on detection breakdown and filter noise of 1D signal,et.. How
to construct 2D mother wavelet from non-orthogonal 1D mother wavelet,
is the question we try to resolve. In this paper, we construct 2D
mother wavelet from the invert projection of 1D mother wavelet. Thus,
we give another way to construct 2D mother wavelet . This nmethod suit
to construct 2D mother wavelet from non-orthogonal 1D mother wavelet.
By this method, we can construct 3D or ND mother wavelet. By this
method, we can construct 2D mother wavelet which can be applied on
detection breakdown and filter noise of 2D signal, et.
