I don't know what LL1 or HH1 are but the 2D discrete Fourier transform should find you the frequency components of the image, in MATLAB it's "fft2".

If you have a support contract, you can call the Mathworks and ask for help from someone such as Wayne King, otherwise you'll have to try in this Answers forum. Search the Answers forum and File Exchange for Wavelet and you'll find lots of people you can contact.
