Threat recognition in complex environments: Gated viewer images fused with thermal ir images and an introduction of contextual dimming

The defense and security community have to cope with threats in complex environments that are merged in the scene context. The aim of this study is to investigate if fusion of Gated Viewer images with traditional thermal IR images provides a solution for threat recognition (with context understanding) in complex environments; and if contextual...

Research topics on EO systems for maritime platforms

Our world is constantly changing, and this has its effect on worldwide military operations. For example, there is a change from conventional warfare into a domain that contains asymmetric threats as well. The availability of high-quality imaging information from Electro-Optical (EO) sensors is of high importance, for instance for timely...

Improved depth perception with three-dimensional auxiliary display and computer generated three-dimensional panoramic overviews in robot-assisted laparoscopy

In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by...

Evaluation of intensified image enhancement through conspicuity and triangle orientation discrimination measures

For many military operations, situational awareness is of great importance. During night conditions, this situational awareness can be improved using both analog and digital image-intensified cameras. The quality of image intensifiers is a topic of interest. One of the differences between a digital and analog system is noise behavior. For...

Supporting Intelligence Analysts with a Trust-based Question-Answering System

Intelligence analysts have to work in highly demanding circumstances. This causes mistakes with severe consequences, which is the reason that support systems for intelligence analysts have been developed. The support system proposed in this paper assists humans by offering support that improves their performance, without reducing them in their...

Assessment methodology of counter-personnel high power electromagnetic millimeter wave effects

The group of NLW that arguably offers the largest amount of useful applications are based on high power electromagnetic millimetre wave technology. This group is often referred to as ‘Active Denial Systems’ (ADS), since they are primarily aimed at deterring and dispersing people out of an area. The effect mechanism involves radiating millimetre...

A search engine for retrieval and inspection of events with 48 human actions in realistic videos

The contribution of this paper is a search engine that recognizes and describes 48 human actions in realistic videos. The core algorithms have been published recently, from the early visual processing (Bouma, 2012), discriminative recognition (Burghouts, 2012) and textual description (Hankmann, 2012) of 48 human actions. We summarize the key...

Maritime Situation Awareness Capabilities from Satellite and Terrestrial Sensor Systems

Semi-hidden target recognition in gated viewer images fused with thermal IR images

Defense and security surveillance scenarios typically involve the detection and classification of targets in complex and dynamic backgrounds. Imaging systems deployed for this purpose should therefore provide imagery that enables optimal simultaneous recognition of both targets and their context. Here we investigate the recognition of semi...

Behavioral profiling in CCTV cameras by combining multiple subtle suspicious observations of different surveillance operators

Camera surveillance and recognition of deviant behavior is important for the prevention of criminal incidents. A single observation of subtle deviant behavior of an individual may sometimes be insufficient to merit a follow-up action. Therefore, we propose a method that can combine multiple weak observations to make a strong indication that an...

Out of the shadow: Long term cost development of intelligent sensor networks

The paper addresses intelligent sensor networks (ISNs) as a special version of networked wireless robotics. The success of these networks is partly explained by the technical advances, but as well by cutting down costs of these networks. Using a functional breakdown of intelligent ISNs, the trends of the various functions are discussed. The...

GOOSE: Semantic search on Internet connected sensors

More and more sensors are getting Internet connected. Examples are cameras on cell phones, CCTV cameras for traffic control as well as dedicated security and defense sensor systems. Due to the steadily increasing data volume, human exploitation of all this sensor data is impossible for effective mission execution. Smart access to all sensor data...

3D Scanning of Dutch Military: Secular Trends in PCA for 18,000 Soldiers

The Netherlands Military Forces started 3D whole body scanning of their recruits in the year 2003. 1D-body dimensions are derived from the scans to supply the best fitting size without human involvement. In order to investigate secular trends in body dimensions, the dataset of 3D scans was cleaned and analyzed for inter-individual differences...

Re-identification of persons in multi-camera surveillance under varying viewpoints and illumination

The capability to track individuals in CCTV cameras is important for surveillance and forensics alike. However, it is laborious to do over multiple cameras. Therefore, an automated system is desirable. In literature several methods have been proposed, but their robustness against varying viewpoints and illumination is limited. Hence performance...

Measuring the performance of super-resolution reconstruction algorithms

For many military operations situational awareness is of great importance. This situational awareness and related tasks such as Target Acquisition can be acquired using cameras, of which the resolution is an important characteristic. Super resolution reconstruction algorithms can be used to improve the effective sensor resolution. In order to...

Automatic Human Action Recognition in a Scene from Visual Inputs

Surveillance is normally performed by humans, since it requires visual intelligence. However, it can be dangerous, especially for military operations. Therefore, unmanned visual-intelligence systems are desired. In this paper, we present a novel system that can recognize human actions. Central to the system is a break-down of high-level...
