WebSep 17, 2024 · It just occurred to me that I wrote a pure python unencumbered implementation of the DT-CWT which might fit into this toolbox here. It's written mostly for algorithmic understanding, not speed (so is very well documented/commented and cleanly implemented), but it is still usable. WebSep 20, 2024 · We compare doing the dtcwt with the python package and doing the dwt with PyWavelets to doing both in pytorch_wavelets, using a GTX1080. The numpy methods were run on a 14 core Xeon Phi machine using intel's parallel python. For the dtwcwt we use the near_sym_a filters for the first scale and the qshift_a filters for subsequent scales. matthew mcquaid npi
