The system is designed for 44 m/s wind speed and 2 m waves. The 10kWp (130 m2) floating solar project was built as a key part of the DUAL Ports EU-funded initiative. On 14th January 2022 a new floating solar power plant was set up by Heliorec in the Port Oostende, Belgium in cooperation with Greenpipe International. The tests folder contains multiple tests to allow independent verification of this toolbox.New 10kWp floating solar installed in the Port of Oostende! and optimizable orthogonal-wavelets are supported.Separable transformations use a 1d transformation along both axes which might be faster since less matrix entriesĮxperimental code to train an adaptive wavelet layer in PyTorch is available in the examples folder. To use a separable transformation, pass separable=True to MatrixWavedec2 and MatrixWaverec2. The process for the 2d transforms MatrixWavedec2, MatrixWaverec2 works similarly.īy default, a non-separable transformation is used. I have testedĭaubechies-Wavelets db-x and symlets sym-x, which are usually a good starting point.Īnalog to the 1d-case wavedec2 and waverec2 rely onĬonv2d, and its transposed counterpart conv_transpose2d. Internally both rely on conv1d, and its transposed counterpart conv_transpose1dįrom the torch.nn.functional module. The functions wavedec and waverec compute the 1d-fwt and its inverse. wavedec( data_torch, wavelet, mode = 'zero'), wavelet)) wavedec( data_torch, wavelet, mode = 'zero', level = 2)) wavedec( data, wavelet, mode = 'zero', level = 2)) # compare the forward fwt coefficients print( pywt. Import torch import numpy as np import pywt import ptwt # use " from src import ptwt " if you cloned the repo instead of using pip. Install the toolbox via pip or clone this repository. finally, this package provides adaptive wavelet support (experimental).single and two-dimensional wavelet packet forward transforms are available via the WaveletPacket and WaveletPacket2D objects,.cwt computes a one-dimensional continuous forward transform,.2d sparse-matrix transforms with separable & non-separable boundary filters are available (experimental),.MatrixWavedec and MatrixWaverec provide sparse-matrix-based fast wavelet transforms with boundary filters,.wavedec3 and waverec3 cover the three-dimensional analysis and synthesis case,.the two-dimensional fwt is called wavedec2 the synthesis counterpart waverec2,.the fast wavelet transform (fwt) via wavedec and its inverse by providing the waverec function,.
