摘要
讨论了L2(R2)空间中连续小波变换,分别得到由一元变换函数构造二元变换函数的二元小波变换及重构公式,得到重构公式在L2(R2)中范数收敛意义下成立的条件.
Wavelet continuous transform in L^2 (R^ 2) are discussed and bivariate wavelet continuous transform and reconstruction formula are derived from wavelet continuous transform. Moreover, the condition for convergence of reconstruction formula in the sense of L^2 (R^2 ) are given.
