2-band discrete wavelet transform (DWT)
Dual-Tree Complex Wavelet Packet-The 2-band discrete wavelet transform (DWT) provides
an octave-band analysis in the frequency domain, but this
might not be ‘optimal’ for a given signal. The discrete wave

在图象中,边缘是由灰度级和相邻域点不同的象素点构成的。因而,若想增强边缘,就应该突出相邻点间的灰度级的变化。微分运算可用来求信号的变化率,因而具有加强高频分量的作用。如果将其应用在图象上,可使图象的轮廓清晰。由于我们常常无法事先确定轮廓的取向,因而挑选用于轮廓增强的微分算子时,必须选择那些不具备空间方向性的和具有旋转不变的线形微分算子。-In the image, the edge is adjacent to the gray-scale and different domains consi
