One of the advantages of the dual-tree complex wavelet transform is that it can be used to implement 2D wavelet transforms that are more selective with respect to orientation than is the separable 2D DWT.
There are two versions of the 2D dual-tr

复杂的二维双树离散小波变换(DWT)同样也引起了小波在六个不同的方向,但是,在这种情况下有两种小波在每个方向将如下所示。在每一个方向,一个两个小波可以被解释为一个复数的真实部分2 d小波,而其他小波可以被解释为一个复数的虚部2 d小波。因为复杂的版本有两倍的小波作为真正的版本的转换、复杂的版本是4次膨胀。复杂的二维双树被实现为四个严格采样可分二维DWTs操作在并行。然而,不同的过滤器集一起使用的行和列。正如在现实情况下,金额和不同的子带图像进行小波得到定向。复杂的二维双树DWT的图像x是由以下函
