Transform Backward method

Hello, I have question in TransformBackward method in the RealFourierTransformation class. I have a real signal in frequency domain and want to transform to time domain and I am using matlabconvention. This method only implement the transformation pair, in other word, if I have signal in time domain...

Re: I need to write Hadamard transform class

Yes, implementing Hadamard transform similar to the FFT transform will be good. But I have problem: I don't understand completely, how did you do FFT. Maybe you can help me to understand, give some more information. Have you read WM_Multimed_IRI'03.pdf? In that doc transform is maked by using...

Re: I need to write Hadamard transform class

Yes, sound interesting indeed. I'm looking forward to integrate it in Iridium! Btw, will such audio watermarks also survive a pitch filter? Might the following link help for a start? Apparently you can implement Hadamard transform similar to the FFT transform (e.g. Cooley-Tukey approach) http://forums...

Re: I need to write Hadamard transform class

Yes. I study in university and must write a course project. I choose theme "Multimedia Watermarking with Complex Hadamard Transform in the Inverse Pyramid Decomposition" when I found this: http://pandora.compsci.ualr.edu/cpsc2382-01/papers/WM_Multimed_IRI'03.pdf It's very interesting...
