+# An Efficient Multi-sensor Fusion Approach for Object Detection in Maritime Environmentt [6]: 
+Robust real-time object detection and tracking are
+challenging problems in autonomous transportation systems
+due to operation of algorithms in inherently uncertain and
+dynamic environments and rapid movement of objects. There-
+fore, tracking and detection algorithms must cooperate with
+each other to achieve smooth tracking of detected objects that
+later can be used by the navigation system. In this paper, we
+first present an efficient multi-sensor fusion approach based on
+the probabilistic data association method in order to achieve
+accurate object detection and tracking results. The proposed ap-
+proach fuses the detection results obtained independently from
+four main sensors: radar, LiDAR, RGB camera and infrared
+camera. It generates object region proposals based on the fused
+detection result. Then, a Convolutional Neural Network (CNN)
+approach is used to identify the object categories within these
+regions. The CNN is trained on a real dataset from different
+ferry driving scenarios. The experimental results of tracking
+and classification on real datasets show that the proposed
+approach provides reliable object detection and classification
+results in maritime environments.
