Announcing YOLTv4: Improved Satellite Imagery Object Detection
Preface: Though CosmiQ Works (and its associated blog: The DownLinQ) has unfortunately been shut down, there remains much to be done in the geospatial analytics domain. Accordingly, this blog details work performed independently of IQT and in my spare time. In a number of previous blogs [e.g. 1, 2, 3] and academic papers [e.g. 4, 5, 6] we've demonstrated the striking efficacy of adapting YOLO to detect objects in satellite imagery. Recall that YOLO is a leading deep learning object detection framework, designed to detect objects in imagery. YOLO maxes out at image sizes of a few thousand pixels in size, far too small to handle large scale satellite imagery which can exceed 100 million pixels.
