Color and Uncertainty: It is not always Black and White

submitted by: alexandertoet
To fully comprehend the meaning and impact of visualized data it is crucial that users are able to perceive and comprehend the inherent uncertainty of the data in a correct and intuitive way. Data uncertainty is frequently visualized through color mappings. Previous studies argued that color hue is not suitable for communicating uncertainty because most hue scales lack an intrinsic perceptual order. In this paper we examine the use of hue for communicating data uncertainty in more detail. We...

Progress in Color Nightvision

submitted by: alexandertoet
I present a sample based color transfer method that gives nightvision imagery a realistic color appearance. The method is specific for different types of materials in a scene and can easily be adapted for the intended operating theatre and the task at hand. Because of its simplicity the method is highly suitable for real-time implementations. In this presentation I will show some nighttime movies that have been registered with prototype camera systems that apply the new color mapping...

INVIS - The Movie

submitted by: alexandertoet
The TNO INVIS system provides a real-time all-weather all-time full color image with a natural color appearance, by fusing Intensified Visual, Near-Infrared and Thermal imagery, using the TNO patented ''Color the Night'' false color mapping principle. The system also provides a virtual 3D representation of the observed environment, and includes a range of different real-time image enhancement techniques, like dynamic noise reduction and superresolution. The INVIS can be used for navigation...

submitted by: schulzbu
The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production geared towards middle school, highschool students and undergraduates as well as viewers who are interested in plant science. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated...
