A simple power-logarithm histogram modification operator is proposed to enhance infrared (IR) image contrast. The algorithm combines a logarithm operator that smoothes the input image histogram while retaining the relative ordering of the original bins, with a power operator that restores the smoothed histogram to an approximation of the original...

Sharing and re-using design knowledge is a challenge for the diverse multi-disciplinary research and development teams that work on complex and highly automated systems. For this purpose, a situated Cognitive Engineering (sCE) methodology was proposed that specifies and assesses the functional user requirements with their design rationale in a...

Various innovations have been identified in assistive technology for the visually impaired. One of these innovations are systems that present feedback and information in a tactile format. These tactile systems have the potential to help the visually impaired, but there is little attention to how it can be combined with other assistive technology...

We present a color-to-gray conversion algorithm that retains both the overall appearance and the discriminability of details of the input color image. The algorithm employs a weighted pyramid image fusion scheme to blend the R, G, and B color channels of the input image into a single grayscale image. The use of simple visual quality metrics as...

The SUPRA research project - Simulation of Upset Recovery in Aviation - has been funded by the European Union 7th Framework Program to enhance the flight simulation envelope for upset recovery simulation. Within the project an extended aerodynamic model, capturing the key aerodynamics during and beyond stall for a large category transport...

This paper investigates how pilots' control behavior and motion perception during a simulated roll maneuver depends on the level of normal g load using a centrifuge-based simulator. Fourteen commercial pilots participated in the study, actively controlling a series of coordinated bank angle changes between -30 and +30 degrees. By changing the...
