In this paper we present an object detection system based on YOLOv2 and transfer learning which is compared to Keras faster RCNN. We evaluate our systems using two infrared datasets: a small dataset of low resolution thermal images and a large dataset of high resolution thermal images both containing the object classes; people and land vehicles. Both detectors are trained on the large dataset of high resolution thermal images and tested using the low resolution images. Fine tuning on the small dataset is implemented to increase the accuracy of the detectors. This research will be of great interest to the defence community as they could save a lot of time and money collecting and annotating data.
