Researchers at the Southwest Research Institute (SwRI) have developed a motion prediction system that enhances pedestrian detection in autonomous vehicles.

The computer vision tool relies on a deep learning algorithm to predict motion by observing real-time biomechanical movements, focusing on pedestrians' pelvic area.

The researchers compared optical flow algorithms to other deep learning methods, including temporal convolutional networks (TCNs) and long short-term memory. The team tested several configurations and optimized a novel TCN that outperformed competing algorithms, predicting sudden changes in motion within milliseconds with a high level of accuracy.

The SwRI algorithm optimizes dilation in network layers to learn and predict trends at a higher level.

The team used a markerless motion capture system, which automates biomechanical analysis in sports science. Then, the system used computer vision and perception algorithms to provide insights into kinematics and joint movement.
