 RoI window might be too small to cover the region of the feature map containing
 information for this object.

+As a solution to this, the Feature Pyramid Network (FPN) \cite{FPN} enables features
 of an appropriate scale to be used, depending of the size of the bounding box.
 For this, a pyramid of feature maps is created on top of the ResNet \cite{ResNet}
 encoder by combining bilinear upsampled feature maps coming from the bottleneck
