A generalization of wavelets that uses vector valued functions as scaling and wavelet functions. The two scale equation contains a sum of matrices instead of sum of scalars.
To perform the GHM multiwavelet transformation in MATLAB, you can use the wavelet toolbox if available. First, define the GHM wavelet filters using the appropriate coefficients. Then, apply the wavedec function for decomposition and waverec for reconstruction. Alternatively, you can implement custom functions based on the GHM wavelet properties if the toolbox does not include it.
Hi When you use two or more wavelet for processing the image its called as Mutiwavelet transformation.Matlab Package for these transformation are available.Dr.Vasily Strela has created the package for it.Google for his name ,You can mail him to get the package.I think its has Matlab 4/5 version compatibility,not very sure of it. If you have any other questions..mail me at rrromeoranjan@gmail.com
