Deep Learning of Semantic Image Labels on HDR Imagery in a Maritime Environment
<p>Situational awareness in the maritime environment can be extremely challenging. The maritime environment is highly dynamic and largely undefined, requiring the perception of many potential hazards in the shared maritime environment. One particular challenge is the effect of direct-sunlight …

An Expected Entropy Reduction (EER) Approach to Target Tracking in Maritime Environment for On-board Camera
Maritime surveillance system installed on-board is crucial in protecting commercial vessels worldwide, which suffer potential losses due to the maritime piracy assault. On-board camera provides a way of monitoring suspicious activities at a low cost. However, the maritime environment poses …

Temporal Frame Difference Using Averaging Filter for Maritime Surveillance
… a lot of attention in the last few decades. Maritime surveillance is the act of effective detection/recognition of all maritime activities that have impact on economy, security or the environment. The maritime environment is a dynamic environment. Factors such as constant moving of waves, sun …

Fishing as a way of life: a cultural geography of fishing communities in Castletownbere (Ireland) and Le Guilvinec (Brittany)
… of the meanings that participants give to their maritime environment emerge through my encounters with three fishing realms − the home, the boat, and the pier. The immersive character of ethnographic methodology allows for a meaningful engagement with participants and their maritime environment. …

A tale of two regions – comparative analysis of maritime security in East and West Africa
The maritime environment in general and maritime security in particular have often been neglected in Africa. In recent years, there has been a new focus on maritime issues but the academic literature on the subject is largely related to counter-piracy operations in East Africa and, to some degree, …

Feature-based object tracking in maritime scenes.
… of various objects on the sea is essential for maritime navigation and collision avoidance. Mariners normally rely on two complementary methods of the monitoring: radar and satellite-based aids and human observation. Though radar aids are relatively accurate at long distances, their capability …

The systems integration of autonomous behavior analysis to create a "Maritime Smart Environment" for the enhancement of maritime domain awareness
Maritime Domain Awareness (MDA) is a very challenging mission area in an ever-increasing net-centric environment, which is inundated with data from many highly advanced, capable sensors and communication suites. With all these technological data collection and dissemination advances, the …

Neutron Response Vectorization and Optimization of Moderating Neutron Spectrometers for Active Interrogation
… passive detection virtually impossible in the maritime environment. Active interrogation, while increasing the radiative signature, also increases the radiative background such that measuring SNM signatures becomes difficult, if not impossible, especially given an unknown and complex …

Beamforming and scan pattern performance evaluation of rotating maritime multi-beam phased array surveillance radar
… performance of different possible targets in the maritime environment per antenna rotation. MATLAB, with various Phased Array Toolbox objects, was used as the platform to create the simulation model. A wide variety of variables were adjusted to test the effect on detection performance per rotation …
