The EBLC strategy can reduce the communication bandwidth usage of a video feed, which allows more videos to be transmitted concurrently through a fixed bandwidth. Furthermore, dynamic EBLC significantly reduces the storage requirements to archive videos for offline analysis. The generated PSMs using our EBLC technique can generate a pedestrian warning to alert connected vehicles and pedestrians, and ultimately improve safety while reducing pedestrian-vehicle conflicts.\u00a0 The vision-based approach generates PSMs in real-time following the standard of the society of automotive engineers (SAE), which can be used by any connected vehicle pedestrian safety applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr. Mashrur \u201cRonnie\u201d Chowdhury led a team at Clemson University developed a computer vision-based software that processes information from video cameras to generate alerts for at-risk pedestrians at intersections.
