The complex 2D Doubletree discrete wavelet transform (DWT) also caused a Wavelet in six different directions, but in this case there are two wavelet in each direction will be as follows. In each direction, a two wavelet can be interpreted as a plural real part of the 2 d wavelet other wavelet can be interpreted as the imaginary part of a complex of 2 d wavelet. Complex version wavelet twice as much as the real version of the conversion, the complex version 4 expansion. The complex 2D Doubletree achieve four rigorous sampling can be divided into two-dimensional DWTs operating in parallel. However, different filter sets with rows and columns. As in the real case, the amount and the different sub-band image to the wavelet get directed. Complex two-dimensional image of Doubletree DWT x is calculated by the following function, cplxdual
