A CWT performs a convolution with data using the wavelet function, which is characterized by a width parameter and length parameter. The wavelet function is allowed to be complex. data on which to perform the transform. WebNov 20, 2024 · FFT is a clever and fast way of implementing DFT. By using FFT for the same N sample discrete signal, computational complexity is of the order of Nlog 2 N . Hence, using FFT can be hundreds of times faster than conventional convolution 7. Therefore, FFT is used for processing in the medical imaging domain too.
