Human Action Recognition in Still Images Using ConViT
share
Understanding the relationship between different parts of the image plays a crucial role in many visual recognition tasks. Despite the fact that Convolutional Neural Networks (CNNs) have demonstrated impressive results in detecting single objects, they lack the capability to extract the relationship between various regions of an image, which is a crucial factor in human action recognition. To address this problem, this paper proposes a new module that functions like a convolutional layer using Vision Transformer (ViT). The proposed action recognition model comprises two components: the first part is a deep convolutional network that extracts high-level spatial features from the image, and the second component of the model utilizes a Vision Transformer that extracts the relationship between various regions of the image using the feature map generated by the CNN output. The proposed model has been evaluated on the Stanford40 and PASCAL VOC 2012 action datasets and has achieved 95.5 mAP and 91.5 state-of-the-art methods.
