一种简单实用的草图编辑手势识别方法

On-line Recognition of Sketching Gesture Using Pattern Matching

联机草绘设计作为一种自然、高效的人机交互方式，继承了传统纸笔草绘设计的优点，弥补了现有CAD软件在处理模糊、不精确信息方面的不足，并日益受到人们的关注。针对联机草绘图形的编辑修改，设计出一套简单、快捷的编辑手势．并采用模式匹配的方法对其进行识别。实验结果表明，提出的方法具有较高的识别效果，加快了概念草图的设计过程。

On-line freehand sketching is a natural and powerful means of human machine interaction.It can have the freedom of sketching on paper with pencil and the benefit of an computer aided design tool.In this paper, first we design a set of natural and efficient gestures for editing sketch,then present a robust method based on pattern matching to handle gesture recognition.The result of experiments shows the proposed method has good recognition performance,and it can accelerate the design of conceptual sketch.
