摘要
针对复小波在实际应用中比实小波更具有优势的特点,给出了紧支撑正交复小波滤波器参数化的更简单的形式,比FENG等(2013)减少了参数的个数,更易于得到正交的复小波,从而为工程人员选择合适的复小波带来更大的便利,并给出了算例.
The complex wavelets have more advantages than real wavelets in some practical applications,In this paper,a simpler form of parameterization for orthogonal complex wavelet filters with compact support are given,The number of parameters is less than that in FENG et al.(2013),It is easier to obtain orthogonal complex wavelets by our method,which will bring more convenience for engineers,Moreover,some examples are given.
