Based on the previous results in wavelet research, a definition of binary wavelet transform for continuous signals is given in the form of convolution in this paper. 在前人工作的基础上,我们运用卷积来定义一个连续信号的二进小波变换。
It is acquired from that it makes use of that the interpolation function of cubic spline interpolation has a continuous third derivative on the base of two-dementional cubic convolution interpolation. 它在二维三次卷积插值法的基础上利用三次样条插值法的插值函数具有三阶连续导数的性质而得来的。
