基于视觉的手势识别技术

近年来计算机已经成为人们日常生活的一部分，人们与计算机的交互也日益成为科研领域的热点。基于视觉的手势识别是实现新一代人机交互所不可缺少的一项关键技术，而手势识别的研究也可促进手语识别的发展，从而消除健全人与聋哑人之间的交流障碍，使他们能获得健全人的正常生活，帮忙他们参加社会的各项活动。文中介绍了手势识别方法的发展、手势识别的技术难点，具体阐述了基于视觉的手势识别系统原理和组成，手势的建模以及在手势识别中常用的技术方法。

Technologies of Hand Gesture Recognition Based on Vision

Computer has been widely used in all parts of people's daily life.The study of the mutual relationship between people and computer has also become the focus of the scientific research.The ability for computer to visually recognize hand gestures is essential for future human-computer interaction.Moreover hand gesture recognition based on vision can promote the sign language recognition development.Sign language recognition can eliminate the exchange barrier between healthy person and deaf-mute,which enables them to obtain the healthy person's normal life,helps them to take part in social activity.Presents the development,technical difficulty and elaborates the system principle and the composition of hand gestures recognition based on vision.Moreover,introduced the modeling of hand gesture and the technique of hand gestures recognition.
