According to randomness and periodicity of power load,a new method for short-term load forecasting is proposed based on 2-D wavelet transform and least square support vector machine(LS-SVM).

Johnstone,a method integrated with an improved threshold function and 2-D wavelet transform,is used to overcome the shortcoming of discontinuity of hard-threshold method and dispersion of the soft-threshold method.

With a 2-D wavelet transform to the image,we implement the image encryption algorithm based on the technique of image scrambling transformation in frequency domain.

A new adaptive method of image de-noising based on two-dimensional wavelet transform and independent component analysis(ICA) is presented.

The directivity of two-dimensional wavelet transformation and its application in FMI image;

Application of 2-D wavelet transformation in eliminating surface wave interference.;

According to characteristics of surface wave disturbance,this paper transforms the seismic signal into a 4-D function related to time,frequency,space and wave number by means of 2-D wavelet transformation,then we can separate surface by making full use of the differences between signal and surface wave in such four aspects as time field,frequency field,space field and wave number field.

By extracting the gloable color kansei features in the HSV color space and according to the theory of golden section,a novel approach for describing the most interesting areas color features was proposed,and 2D Gabor wavelet was c.
