计算机视觉模型中的知识及其表示

计算机视觉模型是计算机完成视觉任务时所要具备的知识.根据任务的需要,确定模型中应当具有哪些知识并选择合适的表示方法,是建立一个计算机视觉系统首先要解决的问题,并将从根本上影响系统的性能.该文将这些知识分为几何知识、物理知识和关系三种类型,概括论述了各类知识的作用和现有的各种表示方法,并特别指出了物理知识在视觉模型中的重要性.

Knowledge and it's Representation of a Computer Vision Model

： Computer vision model is the knowledge for a computer to accomplish a vision task.Determining which kind of knowledge the model should possess and choosing the representation method,this is the first question to be solved before a vision system is established.It may affect the system＇s performance fundamentally.In this paper,knowledge is classified into three kinds,geometric knowledge,physical knowledge and relation.Functions and various representation methods are summarized．The importance of physical knowledge is specially pointed out．
