A human-centric approach to the design and deployment of AI systems aims to support and augment human capabilities. This sounds worthwhile indeed. But what could this look like in a military context? We explored a human-centric approach to the design and deployment of highly autonomous, unarmed Unmanned Aerial Vehicle (UAV), or drone, and an associ...

This paper describes DASH: Delegation to Autonomous Systems within Human-machine teams. The purpose of DASH is to combine ideas from recent progress in human machine interaction to confront current and prospected challenges of distributed delegation and meaningful human control. We describe the design considerations of DASH and illustrate how deleg...

With the latest advances in image sensor technology, cameras are able to generate video with tens of megapixels per frame. These high resolution videos streams offer great potential to be used in the surveillance domain. For ground based systems, gigapixel streams are already used with great effect as illustrated by the ICME 2019 crowd counting cha...

Hyperspectral imaging sensors acquire images in a large number of spectral bands, unlike traditional electro-optical and infrared sensors which sample only one or few bands. Hyperspectral mosaic sensors acquire an image of all spectral bands in one shot. Using a patterned array of spectral filters they measure different wavelength bands at differen...

BACKGROUND The differentiation of (critical) anatomical structures may be risky and time-expensive in endoscopic surgical procedures. Non-invasive optical imaging techniques are popular for surgical guidance applications since they provide accurate, real-time tissue state information, while being non-invasive and non-damaging in itself. 2D hyperspe...

Imaging systems can be used to obtain situational awareness in maritime situations. Important tools for these systems are automatic detection and tracking of objects in the acquired imagery, in which numerous methods are being developed. When designing a detection or tracking algorithm, its quality should be ensured by a comparison with existing al...

Virtual Reality (VR) mediated teleoperation is a relatively new field in robotics which means little is known about the Human-Robot Interaction (HRI). The objective of this study was to investigate the effects of environmental information presentation on Human-Robot Team (HRT) task performance and operator Situation Awareness (oSA).

Hyperspectral (HS) images inherently contain a larger amount of information compared to Red-Green-Blue (RGB) images. Therefore, HS images are preferred when performing pixelwise classification on material properties over color. During recording, the HS data is disturbed by atmospheric effects, such as humidity and illumination changes. For some obj...

Detecting maritime targets with electro-optical (EO) sensors is an active area of research. One current trend is to automate target detection through image processing or computer vision. Automation of target detection will decrease the number of people required for lower-level tasks, which frees capacity for higher-level tasks. A second trend is th...

Virtual Reality (VR) and 360-degree video are set to become part of the future social environment, enriching and enhancing the way we share experiences and collaborate remotely. While Social VR applications are getting more momentum, most services regarding Social VR focus on animated avatars. In this demo, we present our efforts towards Social VR...

Naval ships have camera systems available to assist in performing their operational tasks. Some include automatic detection and tracking, assisting an operator by keeping a ship in view or by keeping collected information about ships. Tracking errors limit the use of camera information. When keeping a ship in view, an operator has to re-Target a tr...

The bottleneck in situation awareness is no longer in the sensing domain but rather in the data interpretation domain, since the number of sensors is rapidly increasing and it is not affordable to increase human data-analysis capacity at the same rate. Automatic image analysis can assist a human analyst by alerting when an event of interest occurs....

Purpose: Early detection of colorectal cancer is key to full recovery. This urged governments to start population screening programs for colorectal cancer, often using flexible endoscopes. Flexible endoscopy is difficult to learn and time-consuming. Automation of flexible endoscopes may increase the capacity for the screening programs. The goal of...

Background and study aims: We introduced a new platform for performing colonoscopy with robotic steering and automated lumen centralization (RS-ALC) and evaluated its technical feasibility. Participants and methods: Expert endoscopists (n = 8) and endoscopy-naive novices (n = 10) used conventional steering and RS-ALC to perform colonoscopy in a val...

Background and aims The steering mechanism of flexible endoscopes has been unchanged for many years, and is considered non-intuitive, non-ergonomic and has a long learning curve. We introduced a new platform for performing colonoscopy with robotic steering and automated lumen centralization (ALC), with the aim to study performance of this platform...

Robotizing flexible endoscopy enables image-based control of endoscopes. Especially during high-throughput procedures, such as a colonoscopy, navigation support algorithms could improve procedure turnaround and ergonomics for the endoscopist. In this study, we have developed and implemented a navigation algorithm that is based on image classificat...

Background Flexible endoscopy is the technology of choice for endoluminal interventions and NOTES. The increased demand of flexible endoscopies requires technological solutions to increase safety and efficiency of endoscopy procedures. We have developed a robotized platform for flexible endoscopy. Automating the navigation of endoscopes could be a...

Background: The design of flexible endoscopes has not changed significantly in the past 50 years. A trend is observed towards a wider application of flexible endoscopes with an increasing role in complex intraluminal therapeutic procedures. The nonintuitive and nonergonomical steering mechanism now forms a barrier in the extension of flexible endo...

Colon cancer screening remains a time-consuming and expensive clinical process. Automating flexible endoscopy has the potential to increase screening efficiency. In this research the images captured by the camera at the endoscope tip are used to find the heading direction of the endoscope. Comparing the current heading direction to the desired targ...

In this study, it was shown that using the optical flow and the focus of expansion, obtained from the monocular camera at the beginning of a colonoscope, (semi-)automated steering of flexible endoscopes might become possible. This automation might help to increase colonoscopy efficiency, but is also applicable in other areas.
