What Happens Next? Anticipating Future Motion by Generating Point Trajectories

arXiv:2509.21592v2 Announce Type: replace-cross Abstract: We consider the problem of forecasting motion from a single image, i.e., predicting how objects in the world are likely to move, without the ability to observe other parameters such as the object velocities or the forces applied to them. We formulate this task as conditional generation of dense trajectory grids with a model that closely follows the architecture of modern video generators but outputs motion trajectories instead of pixels. This approach captures scene-wide dynamics and uncertainty, yielding more accurate and diverse predi

Why this matters
Why now

Advances in generative AI models, particularly in video generation, are enabling new applications in motion forecasting, building on existing computer vision capabilities.

Why it’s important

Predicting future motion from static images has significant implications for autonomous systems, robotics, and surveillance, improving their ability to anticipate and react to dynamic environments.

What changes

The ability to generate dense trajectory grids from single images creates a more robust and nuanced understanding of potential future states, moving beyond simple object detection to predictive dynamics.
