ecto is a dynamically configurable Directed Acyclic processing Graph (DAG) framework. It is being used by researchers at Willow Garage and in industry for prototype applications of object capture and modelling, object recognition, pose estimation and refinement, projector-based augmented reality and chess playing. 物体捕捉和重建，物体识别，姿态估计和细化，基于投射的增强显式，玩chess

$ sudo apt-get install ros-fuerte-ecto
$ sudo apt-get install ros-fuerte-ecto-image-pipeline
$ sudo apt-get install ros-fuerte-ecto-opencv

ecto依靠有向无环图来计算，有向无环图又通过python代码来组织，可以用可视化编程动态生成代码来表示计算过程。
