摘要
提出了一种新的连续小波变换.这种连续小波变换具有高分辨性和自适应性,并且可以减小由于参数在分母上所引起误差,数值积分离散时对参数的选择更具有灵活性,最后的数值实验表明了新的连续小波变换的有效性.
A new continuous wavelet transform is proposed, which has a high resolution and adaptability and may reduce the error of the numerical integral because of parameter appearing in the denominator of the integrand. The parameters can be more flexible adjusted for the discreting numerical integral. The final numerical examples show that this new continuous wavelet transform is valid.
