Human Action Recognition in Still Images Combining CBOW Language Processing and CNN

Quanzhi Gong, Yuxiang Xie, Jie Yan, Xidao Luan

Abstract—In the field of computer vision, human action recognition task is a difficult problem, especially for static images. Traditional action recognition methods rely on local or global features designed manually, which are limited by people‚Äôs visual cognition of image. Therefore, it is difficult to achieve the optimal recognition results. In recent years, the convolutional neural network (CNN) has become popular in the action recognition methods, which usually improve the performance by designing network structure. Most of the previous methods solve this task through the implicit image content association information contained in the image. Due to the lack of interpretability of convolution network, it is difficult to judge which part of image information plays an important role, so it is hard to optimize the network model by strengthening some image features. This paper proposes a method of action recognition which combines language processing technology with CNN. The proposed method uses the continuous bag-of-words (CBOW) model to assist CNN to complete the action recognition task by taking the cooccurrence information of the object pairs explicitly. The method is tested on two public datasets, namely Stanford 40 action and Pascal VOC Action 2012. The comparison result with the state-of-the-art methods shows that, as an exploration on the combination of language model and general CNN, the proposed method is satisfactory, whose accuracy rates reach 91.4% and 85.9% respectively.
