WebFlowNetPytorch. This repository is a torch implementation of FlowNet, by Alexey Dosovitskiy et al. in PyTorch. See Torch implementation here. This code is mainly inspired from official imagenet example . It has not been tested for multiple GPU, but it should work just as in original code. The code provides a training example, using the flying ... A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering, … See more The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid. Typically there are two surfaces (boundaries) which are at constant … See more Irregular points (also called singularities) in the flow field occur when streamlines have kinks in them (the derivative doesn't exist at a point). This can happen where the bend is outward (e.g., the … See more • Potential flow (the flow net is a method for solving potential flow problems) • Analytic function (the potential and streamfunction plotted in flow nets … See more The first flow net pictured here (modified from Craig, 1997) illustrates and quantifies the flow which occurs under the dam (flow is assumed to be … See more Darcy's law describes the flow of water through the flow net. Since the head drops are uniform by construction, the gradient is inversely … See more Typically flow nets are constructed for homogeneous, isotropic porous media experiencing saturated flow to known boundaries.

FlowNet2.0首先提到FlowNet1.0没有将FlowNetC和FlowNetS在同等条件下做对比实验，所以得出来的孰优孰劣不够准确。. 这篇文章在FlowNet的基础上提出了三个点，其一是training data的训练策略，其二是提出了stacked architecture ...
WebTherefore, we slightly modified the original FlowNetS architecture and removed the stride 2 in the first layer. We made the beginning of the network deeper by exchanging the 7×7 and 5×5 kernels in the beginning with multiple 3×3 kernels2. Because noise tends to be a problem with small displacements, we add convolutions between the upconvolutions to … WebDec 3, 2024 · 实验时FlowNetS和FlowNetC各包含三种配置: 默认, +v: 变分方法, +ft: 微调. 其中微调是用数据集Sintel的Clean和Final版本以 \(1e-6\) 的学习率进行的. 结果总结如下: 除Chairs数据集外, 传统方法都要比本文的方法好. 说明了神经网络方法在大数据集下可以表现的 …
