In the dualtree complex wavelet transform (DT-CWT), two different filterbanks are executed in parallel to analyze a given input signal, which increases the amount of data after analysis. DT-CWT leads to a redundancy factor of 2 d for d-dimensional signals. In the proposed single-tree complex wavelet transform (ST-CWT) structure, filters of the lifting filterbank switch back and forth between the two analysis filters of the DT-CWT. This approach does not increase the amount of output data as it is a critically sampled transform and it has the desirable properties of DT-CWT such as shift-invariance and directional selectivity. The proposed filterbank is capable of constructing a complex wavelet-like transform. Examples are presented. © 2012 IEEE.TurkishComplex wavelet transformsDirectional selectivityDual-tree complex wavelet transformInput signalLifting structureOutput dataRedundancy factorsShift-invarianceTime varyingFilter banksForestryAnalysisData ProcessingDirectional MeasurementFiltersSignalsConference Paper10.1109/SIU.2012.6204747
