About the Project

The FLIR team is working on real time object detection models with a primary use for autonomous driving cars. Much of the current technology is centered around RGB cameras as seen in Figure 1. 

While RGB sensing is a de facto standard in real time object detection models it is not without its weaknesses and must be used in conjunction with other sensing technology to provide reliably safe object detection for autonomous driving.

Figure 2 depicts a scene behind the lens of an RGB sensor on the left and the object detection of a thermal sensor on the right. RGB sensing tends to fail at night due to the reduced color space, which poses a large risk for the safety of autonomous driving cars. FLIR as a company specializes in the design and production of thermal imaging cameras, components, and imaging sensors, and hopes to leverage that technology in the field of computer vision.

This project is primarily concerned with analyzing the robustness of a thermal object detector for ADAS (Advanced Driver Assistance Systems) subject to the effect of added noise. Understanding the effect of noise is incredibly important to the field of computer vision. It has been observed that small amounts of noise can result in severe misclassifications. The team is also exploring adversarial attacks (adding inputs to a model to intentionally cause misclassifications) in an attempt to make the object detection models as robust as possible.
