步骤二:构建PWCNet模型 在这一步中,我们将构建PWCNet的深度学习模型。PWCNet使用卷积神经网络架构,你可以选择使用TensorFlow或者PyTorch等深度学习框架来构建模型。 以下是一个使用PyTorch构建PWCNet模型的代码示例: AI检测代码解析 importtorchimporttorch.nnasnn# 定义PWCNet模型classPWCNet(nn.Module):def__init__(s...

这里的pytorch的实现使用了Probability integral transform(概率积分变化)。这个定理应用在指数分布上就是,如果从均匀分布(0,1)中选取随机变量,对变量做-log,那么就相当于是在指数分布中随机选取变量,反之,对指数分布中的随机变量做-exp,就相当于是在均匀分布(0,1)中选取随机变量。根据这个定理,我们做u~U(0,1) ...

The PyTorch implementation almost matches the Caffe implementation (average EPE on the final pass of the Sintel training set: 2.31 by Pytorch and 2.29 by Caffe). Network Architecture PWC-Net fuses several classic optical flow estimation techniques, including image pyramid, warping, and cost volume,...
