A Simple but Effective Downsampling Module For Semantic Segmentation

1. install pytorch_wavelets git clone https://github.com/fbcotter/pytorch_wavelets cd pytorch_wavelets pip install . Please refer for more details: https://github.com/fbcotter/pytorch_wavelets

2. install semantic segmentation package pip install segmentation-models-pytorch Please refer for more details: https://github.com/qubvel/segmentation_models.pytorch

3. You can replace the downsample method, like maxpooling, averagepooling, convolution with stride, with our HWD directly.
