High-dimensional wavelet analysis is a powerful tool to analyze and deal with multidimensional signal.The key of construction of orthogonal scaling function and wavelet function is construction of wavelet filters.There existed obvious fault constructing wavelet filters by tensor product.This paper offered a method constructing conjugate quadrature filter of bivariate wavelet based on cosine function.
