Zhong Zhang, Satoshi Horihata, Tetsuo Miyake, Hiroshi Toda · 2005
In this study, we propose a 2-dimensional translation invariant Real-Imaginary Spline Wavelet (RI-Spline wavelet) and develop a 2-dimensional Complex Discrete Wavelet Transform (2-D CDWT). The main results obtained can be summarized as follows: 1) The problem of 2-D translation variance which is caused by the DWT using a real mother wavelet can be solved by using the 2-D RI-Spline wavelet. 2) The 2-D RI-Spline wavelet is applied to image processing, and encouraging results are obtained.
