【摘要】 <正> 1 引言手语是聋哑人使用的语言。它是由手形动作辅之以表情姿势而构成的比较稳定的表达系统,是一种靠动作/视觉进行交际的特殊语言。手语识别系统与手语合成系统,共同构成“人-机手语翻译器”,为聋哑人提供更好的服务。人类交互往往声情并茂,除了采用自然语言(口语、书面语言)外,人体语言(表情、体势、手势)也是人更多还原

【Abstract】 Sign Language is the language used by deaf-mute. In this paper the ANN/HMM-based sign language recognition method is proposed. Feature-mapper on posture , position and orientation is built respectively using ANN. The feature vector composed of output from each feature-mapper is used as input of HMM. In addition, in the process of building feature-mapper on posture, multi-feature multi-classifier fusion algorithm is presented. It is proved by experiment that ANN/HMM-based sign language recognition method is feasible and effective.更多还原
