fftLoss
The fftLoss @PyTorch is a frequency domain loss function that prevents the problem of weak frequency components being suppressed by strong frequency components when using a regular loss function.
思路说明
在使用MSE等从时域或空域计算的损失函数时,常常得到模糊的结果.这是由于强势频率压制了弱势频率的表达.通过在频域对相位和幅值分别计算差异缓解了这个问题.这使得网络更偏向于生成边缘锐利的结果.
Install
pip install fftLoss
Use
from fftLoss import fftLoss
...
loss=fftLoss(input,target,dim=-1,meanOut=True,norm="ortho",absGain=1,angleGain=1)
