The pre-processing step done in this filter is similar to LSSC- it groups similar patches within an image into 3D patch cubes and subsequently applies wavelet transform method over them.
where, * denotes the complex conjugate, [delta]t is the (sampling) time interval between two consecutive points in the time-series and s is the wavelet time scale which provides a measure of the width of [psi] in time.
Wavelet Transforms (WTs) is chosen to overcome the disadvantages of Short Time Fourier Transform (STFT) that provides constant resolution for all frequencies because it uses the same window for the analysis of the inspected signal x (t).
Wavelet transform is a simple and reliable tool for signal and image processing and has overcome the limitations of the Fourier transform.
