The rapid development of society makes people pay more attention to the quality of the environment for children's growth. However, due to the differences of young children, different environments are often needed for cultivation in dynamic interaction scenarios. Therefore, the authors propose an environment creation method for children's behavior classification to improve the quality of children's growth environment. Taking the video data of children for a period of time as input, the encoder and decoder are designed to classify children's behavior and obtain behavior characteristics. After the input image is processed by the backbone network DCNN, two outputs are obtained, which are four times of shallow features and 16 times of high-level features. Aiming at the semantic gap between environmental features and children's behavior features, the DenseNet model is used to remove the semantic difference between children's behavior features and environmental features, and the similarity between the two features is fitted as much as possible. The dense blocks obtained by different expansion factors of the network are used for feature connection, so that the model is suitable for feature similarity calculation of different modes. The experimental results show that this method can accurately classify children's behavior, and the F value is more than 70%, which can provide prerequisites for children's environment creation. This environment creation model can clearly point out the suitable environment for children and provide a guarantee for children's growth.
社会的快速发展使人们更加关注儿童成长环境的质量。然而,由于幼儿存在差异,在动态交互场景中进行培养往往需要不同的环境。因此,作者提出一种用于儿童行为分类的环境创建方法,以提高儿童成长环境的质量。以一段时间内儿童的视频数据作为输入,设计编码器和解码器对儿童行为进行分类并获取行为特征。输入图像经骨干网络DCNN处理后得到两个输出,分别是四倍下采样的浅层特征和十六倍下采样的高层特征。针对环境特征与儿童行为特征之间的语义鸿沟,采用DenseNet模型消除儿童行为特征与环境特征之间的语义差异,并尽可能拟合两者特征的相似度。利用网络不同扩展因子得到的密集块进行特征连接,使模型适用于不同模式的特征相似度计算。实验结果表明,该方法能够准确地对儿童行为进行分类,F值超过70%,可为儿童环境创建提供前提条件。这种环境创建模型能够明确指出适合儿童的环境,为儿童成长提供保障。
