Deep learning has been well studied for its application to image classification, object detection, and other visible spectrum tasks. However, deep learning is only beginning to be considered for applications in the long-wave infrared (LWIR) spectrum. In this work, we attempt to quantify the imaging system parameters required to perform specific deep learning tasks without significant pre-processing of the LWIR images or specialized training. We show the capabilities of uncooled microbolometer sensors for Fast Region-based Convolution Neural Networks (Fast R-CNN) object detectors and the extent to which increased sensitivity and resolution will affect a Fast R-CNN object detector's performance. These results provide guidelines for design requirements for uncooled microbolometers in industries such as commercial autonomous vehicle navigation that will use deep learning object detectors.
