Research on 3D Convolutional Neural Network and Its Application to Video Understanding

3D Convolutional Neural Network (3D CNN) has been a hot topic in deep learning research over the last few years and has made great achievements in computer vision. Despite years of research and abundant results, a comprehensive and detailed review of this content is still lacking. In this paper, the 3D convolutional neural network is introduced in the following aspects. Firstly, the rationale and model structure of 3D convolutional neural network are put forward. Then the improvement of 3D convolutional neural network is summarized from the network structure, network interior and optimization methods. After that the application of 3D convolutional neural network to the field of video understanding is explained. Finally, the contents summary of the paper and future development. This paper provides a systematic review of the latest research progress of 3D convolutional neural networks and their applications in the field of video understanding, which is of positive significance to the research and development of 3D convolutional neural network.
