I find that these values are multiplied by the upsampled optical flow.But I am not clear what's the meanning of these operations.Why the upsampled optical flow need to multiply corresponding...

output*mask in warp

Hi, I have no idea why mask is needed following code in PWC-Net/PyTorch/models/PWCNet.py mask = torch.autograd.Variable(torch.ones(x.size())).cuda() mask = nn.functional.grid_sample(mask, vgrid) # if W==128: # np.save('mask.npy', mask.cpu().data.numpy()) # np.save('warp.npy', output.cpu().data.numpy()) mask[mask0]...

The parameter appears in PWC-Net/PyTorch/models/PWCNet.py line69 “self.corr = Correlation(pad_size=md, kernel_size=1, max_displacement=md, stride1=1, stride2=1, corr_multiply=1)”，what does the parameter corr_multiply mean?
