| Abstract: | In this paper,we summarize the theory and designing methods of contourlet transform.First,we explain the multidimensional multirate system,which is the key technique to achieve the multidirectional filter by contourlets,and give detail steps how to get directional filter banks from fan filters.Then we further introduce two main designing methods of fan filters based on McClellan transform and polyphase matrix.Finally,we construct a group of parameterized fan filter banks with size 9 by 9. |
