I have designed triplet half-band filer bank. I have got the co-efficients. Can any one help me design wavelet using these co-efficients using MATLAB???

I am a new comer in image processing/ signal processing. I am struggling to write my own codes using MATLAB. So I need help to write code for triplet half band filter bank. Plz help me.

When you say triplet half-band filter bank are you talking about a frame filter bank with one lowpass and two highpass filters. The so-called double-density wavelet transform?

If so, that is available in the Wavelet Toolbox.

Dear Sir,

I am talking about a two channel filter bank with analysis synthesis filters. May you plz. tell me how to input the user defined filter co-efficient and then draw the phi and psi graphs??? I will be thankful to you.
