grid_sample是深度学习中常用的图像处理操作之一,其原理是基于空间变换网络(Spatial Transformer Network,简称STN)的一种操作。STN是一种能够自动学习图像几何变换的网络模块,而grid_sample则是STN的核心组成部分,用于实现对输入图像进行采样的功能。 我们来了解一下STN的原理。STN的目标是通过学习一个空间变换的
gird的shape(4D case)是(N,H o u t,W o u t,2)(N,H_{out},W_{out},2)(N,Hout,Wout,2),这里的H和W是output的长和宽,有一点需要注意的是,grid_sample的output shape是(N,C,H o u t,W o u t)(N,C,H_{out},W_{out})(N,C,Hout,Wout),所以output的shape和grid的shape是一样的,...

1 在这个例子中，将展示给大家如何根据水深点来对网格进行局部加密，其完成实例如图所示。该经验仍然以Delft3D自带的示例为主 2 步骤一：启动RGFGRID（网格生成器），并将工作空间设置到<river>。3 步骤二：打开已有网格<river.grd>打开过程：file——import——grid（RGFgrid）界面如图。4 步骤三：打开水深点文件<...
adsorbates/ A6845D Adsorption and desorption kineticsevaporation and condensationIt is shown that the grid temperature determines the desorption rate of the Spontaneous Desorption for a given sample voltage. The sample temperature has only a minor effect on the rates. From these observations it is ...
