Human‐centered attention‐aware networks for action recognition

Abstract

Action recognition in video is a research hot spot in the field of computer vision. Learning important clues in video context has significant effect to promote the interaction prediction and gesture recognition. Most existing methods infer the interactions between actor and context through relational reasoning methods. While these relational features contribute to improve the salience of action performance, the error will occur when the salient region is irrelevant to the recognized action. Therefore, this paper establishes a human‐centered attention mechanism that dynamically highlights regions associated with action recognition according to target appearance to selectively recognize the human‐object interaction action. The effectiveness of the proposed mechanism is verified on the AVA2.2 data set, and the visualized attention map further shows that the proposed attention mechanism can effectively recognize human‐centered strongly correlated action.

A Robust Visual SLAM Method for Additive Manufacturing of Vehicular Parts Under Dynamic Scenes

“…On this basis, the computer algorithms are used to precisely connect each layer FIGURE 1: A typical example that illustrates scenarios of robust visual SLAM for additive manufacturing to form a layer stack to quickly realize the additive manufacturing of parts [16], [17]. Contemporarily, the application of additive manufacturing technology has bee more and more general in the automotive industry [18], [19],liu2022human. In this context, some brand-name automotive companies currently choose to use additive manufacturing technology in the automotive development stage to achieve the purpose of rapid verification and optimization of components [20], [21].…”

Design of an Intelligent Educational Evaluation System Using Deep Learning

“…Notable applications of deep learning include image classification, speech recognition, and autonomous driving [3]. Along with excellent classification results, DNNs may also exhibit incorrect behavior due to hidden defects, which can lead to serious accidents and losses [4], [5]. To ensure safety, like conventional software, testing techniques are often used to detect incorrect DNN behavior and improve DNN quality [6].…”
