第40届中国控制会议

作者： Haoyang Luo Haikuan Wang Wenju Zhou Kangli liu Jinqi fu School of Mechatronic Engineering and Automation Shanghai University Shanghai Key Laboratory of Power Station Automation Technology Shanghai University

Hand gesture recognition applied in human-computer interaction（HCI） is a useful but challenging task because of the low inter-class and high intra-class variability. It is difficult to improve real-time performance while ensuring accuracy. Since simple but robust features are crucial for the performance of recognition, we proposed the weighted depth difference motion history image（WDD-MHI） to extract spatial-temporal information. Subsequently, a weighted random forest classifier with second training is employed for action classification. The developed method is shown to be computationally efficient allowing it to run in real-time. We designed a multimedia video-wall control system based on online gesture recognition, the recognition results indicate competitive performance of our method over the other methods.

音乐是一种听觉艺术形式,在儿童教育和发展中,尤其是语言能力发展中扮演着重要角色。语音意识是个体感知识别、分析和运用语音的能力,是预测儿童语言读写能力的重要指标。本文梳理了近十年来音乐训练影响儿童语音意识的研究证据,并讨论了音乐训练可能促进语音意识的神经基础和解释模型。大量研究表明,音乐训练可以在行为水平提高儿童在语音意识测量任务上的成绩。此外,音乐训练从两方面影响语音加工的神经基础:一方面通过影响皮层下基本听觉神经通路与大脑听觉皮层,促进儿童前注意水平的语音感知能力;另一方面通过影响语音加工大脑区域间的功能连接,促进语音编码,强化语音加工的听觉-运动整合功能。相关神经机制为音乐训练促进儿童的语音意识提供了生物学基础。基于已有研究,本文提出综合的层级模型对音乐训练影响儿童语音意识的认知神经机制进行系统的解释,该模型认为音乐训练影响语音意识的认知神经机制分为3个层级:第一层级,音乐训练通过影响基本听觉神经通路促进了语音的基本听觉加工,其中节奏训练促进对语音时长信息的感知,音高训练促进对语音频率信息的感知;第二层级,音乐训练通过影响语音加工的神经网络,进一步促进语音编码,其中节奏训练主要促进辅音、韵脚和音节的识别和编码,音高训练促进元音、韵脚和音节的识别和编码;第三层级,音乐训练通过增强听觉与运动脑区之间的信息整合,增强语音运动表征,以及听觉-运动整合能力,进一步提高了语音表征的质量。该领域的研究不但可以揭示人类语言发展的认知神经机制,而且在儿童教育领域具有非常重要的现实意义和应用价值。
