Moving Target Detection Using Infrared Sensors
Arisa Kitagishi, Babak Ebrahimi, Dr. Abhijit Mahalanobis University of Central Florida Introduction Methods Results To provide better object detection using infrared sensors as not many computer vision research focus on frames obtained from infrared sensors. We would like to provide fast and accurate predictions using our network to be able to utilize it in real-life situations. Our goal is to achieve 80% or more in recall with less than 0.1 false alarm rate at long ranges (more than 4km). We initially had background subtraction alone to see the results FoveaNet Then, we applied CNN to it to improve the results Faster RCNN performed about 60% lower recall at false alarm rate of 1.1 compared to our method. Faster RCNN tends to have high false alarm rate when targets were detected. Without CNN Without CNN Background Subtraction Results/ Experiments Dataset Data Ground Truth Prediction We plotted the results using constant false alarm rate to eliminate outlier caused by the low threshold NVESDA ATR Development Dataset: Taken using infrared sensors Contains 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, and 5km ranges Contains night and day time folders Each video contains 1800 frames What we utilized: 2 furthest ranges (4.5km and 5km) Night and Day folders 34 videos The recall increased more than 15% at false alarm rate of 0.5 and even more for smaller false alarm rates by incorporating the CNN in the process. With CNN Faster RCNN CNN References Background Subtraction 1.
