This work deals with the problem of radiometric inhomogeneities found on the physical color images of the anatomical cryosections from the Visible Human Project (VHP) male body. Our goal is to extract very thin structures, like the blood vessel tree from the lungs. Current segmentation methods applied to VHP color images are disturbed by discontinuous,(More)
In support of the recent vision for humans to return to the Moon, we are studying decision support for planetary surface traversals. A key aspect of this investigation is the appropriate role allocations and balance between automation and human participation in the decision process. Some degree of automation is necessary during on-route replanning because(More)
A significant trend in command and control human-systems integration is the design of decision-support systems that attempt to facilitate collaboration between the human operator and automation. Unfortunately, there currently is no framework that explicitly describes different aspects of human-computer collaboration. There is a large body of literature(More)
Laser-scan acquisitions were obtained from real human heads and processed for the construction of a database of anthromo-morphical phantoms for dosimetry studies of hand-held mobile phones. Raw data was converted to cylindrical range images and several image processing techniques were then applied to filter and smooth the profiles for 3D-model construction.(More)
Human intent is an integral part of real-time path planning and re-planning, thus any decision aiding system must support human-automation interaction. The appropriate balance between humans and automation for this task has previously not been adequately studied. In order to better understand task allocation and collaboration between humans and automation(More)
Path planning is a problem encountered in multiple domains, including unmanned vehicle control, air traffic control, and future exploration missions to the Moon and Mars. Due to the voluminous and complex nature of the data, path planning in such demanding environments requires the use of automated planners. In order to better understand how to support(More)
Guidelines for designing you-are-here (YAH) maps aboard International Space Station (ISS) are proposed, based on results from previous 3D spatial navigation studies conducted by our research group and colleagues. This paper reviews terrestrial YAH maps, the common errors associated with them, and how to appropriately implement what is known from terrestrial(More)
Future planetary extravehicular activities (EVAs) will go beyond what was experienced during Apollo. As mission duration becomes longer, inevitably, the astronauts on the surface of the Moon and Mars will actively plan and re-plan their own sorties. To design robust decision support aids for these activities, we have to first characterize all the different(More)
