Vision-based Object Detection and Tracking

Detect and track multiple objects such as pedestrians, bicyclists, and vehicles using a monocular camera mounted on a moving vehicle ! Through a collaboration with General Motors, first half of my PhD work focused on a real-time implementation of vision-based object detection and tracking framework which can be applied to automotive safety applications. To this end, I have been developing a detection system based on Pedro Felzenszwalb's Deformable Part-based Models (with star-cascade algorithm) and a fast tracking system based on the Kalman filter. The system is well integrated into our new vehicle, Autonomous Cadillac SRX4, and shows a promising pedestrian/bicyclist detection performance and an amazing vehicle/motorcycle detection performance !

Our research group at CMU (a.k.a ADCRL, Autonomous Driving Collaboration Research Lab.) performed an amazing engineering work for building a beautiful self-driving vehicle as shown below. Some important aspects of the efforts were introduced in the following paper:
