Spatial-Temporal Behavior Understanding

From the perspective of computer vision to achieve human visual function, an important task is to interpret the scene, make decisions, and guide actions by processing the images obtained from the scene. To do this, it is necessary to judge which objects are in the scene and how they change their position, attitude, speed, relationship, etc., in space over time, as well as their changing trends. In short, it is necessary to grasp the actions and activities of the scene in time and space, determine the purpose of the actions and activities, and then understand the semantic information they convey.
