SSD (Single Shot Multibox Detector) is one of the most successful object detectors for its high accuracy and fast speed. However, features from shallow layer (mainly Conv4_3) lack semantic information, resulting in poor performance small objects. In this paper, we proposed DDSSD (Dilation Deconvolution Single Detector), an enhanced with a novel feature fusion module which can improve over detec...

abstract background: with respect to the difference in the interaction of thermal neutron and x rays with matter, using two radiography systems of thermal neutron and x rays will yield highly valuable information for studying the inner structure of biologic samples. methods: the high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool i...
