Automatic vegetation identification plays an important role in many applications including remote sensing and high performance flight simulations. This paper proposes a novel method that identifies vegetative areas in satellite images and then alters vegetation color to simulate seasonal changes based on training image pairs. The proposed method first generates a vegetation map for pixels corresponding to vegetative areas, using ISODATA clustering and vegetation classification. The ISODATA algorithm determines the number of clusters automatically. We then apply morphological operations to the clustered images to smooth the boundaries between clusters and to fill holes inside clusters. Six features are then computed …
Architecture, Design, And Implementation Of A Rapidly Prototyped Virtual Environment For A Military Spaceplane, Scott A. Rothermel
Architecture, Design, And Implementation Of A Rapidly Prototyped Virtual Environment For A Military Spaceplane, Scott A. Rothermel
Theses and Dissertations
The new Global Engagement vision places increased emphasis on the Air Force's ability to control and exploit space. A military spaceplane combining reliable access to space, high operational tempos, and multi-mission capabilities is in conceptual stages of development. Virtual environment technology provides an opportunity to investigate system requirements and unconventional interface paradigms for this unique vehicle. A virtual environment architecture and design based on support for a rapid prototyping development process, separation of concerns, and user interface development is presented. The rapid prototyping process allowed management of changing requirements via an evolutionary approach to implementation. Separation of the activities performed …
Effect Of Joystick Versus Control Yoke Use On Personal Computer (Pc) Flight Training: A Comparative Analysis, Gregory Alan Fontaine
Effect Of Joystick Versus Control Yoke Use On Personal Computer (Pc) Flight Training: A Comparative Analysis, Gregory Alan Fontaine
Master's Theses - Daytona Beach
The purpose of this study was to provide a comparative performance analysis of a generic control yoke device and a generic joystick device. The comparison provided data needed for further evaluation of personal computer (PC) aircrew training device (ATD) potential. Both devices were used in support of the same PC flight simulation software program, and were evaluated using the experimental research method. Objective and subjective data were obtained during controlled testing, and subsequently analyzed using basic summation and t-test methods. The results tested the research hypothesis that there is no significant difference in personal computer ATD operator performance using a …
