Query: Broad Area Search and Detection of Surface-to-Air Missile Sites Using
  Spatial Fusion of Component Object Detections from Deep Neural Networks   Here we demonstrate how Deep Neural Network (DNN) detections of multiple
constitutive or component objects that are part of a larger, more complex, and
encompassing feature can be spatially fused to improve the search, detection,
and retrieval (ranking) of the larger complex feature. First, scores computed
from a spatial clustering algorithm are normalized to a reference space so that
they are independent of image resolution and DNN input chip size. Then,
multi-scale DNN detections from various component objects are fused to improve
the detection and retrieval of DNN detections of a larger complex feature. We
demonstrate the utility of this approach for broad area search and detection of
Surface-to-Air Missile (SAM) sites that have a very low occurrence rate (only
16 sites) over a ~90,000 km^2 study area in SE China. The results demonstrate
that spatial fusion of multi-scale component-object DNN detections can reduce
the detection error rate of SAM Sites by $>$85% while still maintaining a 100%
recall. The novel spatial fusion approach demonstrated here can be easily
extended to a wide variety of other challenging object search and detection
problems in large-scale remote sensing image datasets.
