Spatio-temporal action detectionGraph neural networksAtomic visual actionsModeling person interactions with their surroundings has proven to be effective for recognizing and localizing human actions in videos. While most recent works focus on learning short term interactions, in this work, we consider ...
Research in action detection has grown in the recent years, as it plays a key role in video understanding. Modelling the interactions (either spatial or temporal) between actors and their context has proven to be essential for this task. While recent works use spatial features with aggregated te...
The input tensor of video data includes temporal, spatial, and channel dimensions, crucial for extracting complementary spatial, temporal, and spatio-temporal features for video action recognition. To efficiently extract and integrate these features, we propose an efficient spatio-temporal module (ESTM)...
Spatio-temporal action detection encompasses the tasks of localizing and classifying individual actions within a video. Recent works aim to enhance this process by incorporating interaction modeling, which captures the relationship between people and their surrounding context. However, these approaches have ...
Human action recognition has drawn much attention in the field of video analysis. In this paper, we develop a human action detection and recognition process based on the tracking of Interest Points (IP) trajectory. A pre-processing step that performs spatio-temporal action detection is proposed. ...
Spatio-temporal Action Detection. Different from VOD, action detection task pays attention to identifying and lo- calizing human actions in the video. The frame-level de- tectors [56, 69] generate final action tubes by linking frame level detection ...
