Compactly supported orthogonal wavelet filters are extensively applied to the
analysis and description of abrupt signals in fields such as multimedia.
Based on the application of an elementary method for compactly supported
orthogonal wavelet filters and the construction of a system of nonlinear
equations for filter coefficients, we design compactly supported orthogonal
wavelet filters, in which both the scaling and wavelet functions have many
vanishing moments, by approximately solving the system of nonlinear
equations. However, when solving such a system about filter coefficients of
compactly supported wavelets, the most widely used method, the Newton
Iteration method, cannot converge to the solution if the selected initial
value is not near the exact solution. For such, we propose optimization
algorithms for the Gauss-Newton type method that expand the selection range
of initial values. The proposed method is optimal and promising when
compared to other works, by analyzing the experimental results obtained in
terms of accuracy, iteration times, solution speed, and complexity.
