I developed an deformable surface tracking demo based on Ngo's work[1].

The blue mesh in the video is the projection of the resulting 3D surfaces using ground truth keypoint matches while the red dots denote the projections of the mesh vertices onto the ground-truth surface.

NVIDIA Jetson Nano使用Gnome3作为默认桌面，在使用NoMachine远程登录后，会十分卡顿。为了优化体验，使用轻量级的Xfce桌面代替Gnome3，实际体验会有很大的提升[1]。

  1. 安装Xfce：
sudo apt install xfce4
  1. 修改NoMachine配置文件，使得远程登录时使用Xfce桌面[2]：
sudo vim /usr/NX/etc/node.cfg

找到DefaultDesktopCommand并且修改为 DefaultDesktopCommand "/usr/bin/startxfce4"

  1. 重启电脑，在登录界面按F1 + ALT + Ctrl进入命令行界面并且登录。
  2. 关掉lightdm并且重启nxserver：
sudo systemctl stop lightdm
sudo /usr/NX/bin/nxserver --restart
  1. NoMachine客户端登录，就会发现打开的是Xfce桌面了。
