Abstract:

This note focuses on the problem of  matrix extension in the theory of  multivariate wavelets and filter banks. In [7], a matrix extension method was given for low-pass filter with linear phase in the bivariate case with special dilation matrix 2I2×2. The authors extend this result to general case with the determinant of the dilation matrix being 4.

Key words: Multivariate wavelets, Filter banks, Matrix extension
