Fluorescent effects have been observed for thousands of years. Stokes, in 1852, began the science of fluorescence culminating in his law of fluorescence, which explained that fluorescence emission occurs at longer wavelengths than the excitation wavelength. This phenomenon is observed extensively in the art world. Daylight fluorescent colors known as Day-Glo have become an artistic medium since...

The Radiance Enhancement (RE) method was introduced for efficient detection of clouds from the space. Recently, we have also reported that due to high reflectance combustion-originated smokes, this approach can be generalized forest fires by retrieving and analyzing datasets collected a space orbiting micro-spectrometer operating in near infrared spectral range. In our previous publication, per...

The National Physical Laboratory, Queens Road, Teddington, Middlesex, TWll OLW, United Kingdom An intercomparison of radiance temperature scales lias been performed by the National Physical Laboratory (NPL) and the National Institute of Standards and Technology (NIST) using a standard transfer pyrometer operating at a wavelength of approximately 1000 nm. It was found that the radiance temperatu...

Interacting with environments exhibiting the subtle lighting effects found in the real world gives designers a better understanding of the scene’s structure by providing rich visual cues. The major hurdle is that global illumination algorithms are too inefficient to quickly compute their solutions for reasonably sized environments. When motion is allowed within the environment, the problem beco...

The time complexity of Monte Carlo radiosity is discussed, and a proof is given that the expected number of rays required to produce a statistical radiosity solution below a speci ed variance for N zones is O(N ). A satisfactory solution is de ned to be one in which the variance of radiance estimates for each zone is below a prede ned threshold. The proof assumes that the radiance is bounded, a...

The Display Simulation Toolbox (DST) is an integrated suite of software tools that help the user characterize the key properties of display devices and predict the radiance of displayed images. Assuming that pixel emissions are independent, the DST uses the sub-pixel point spread functions, spectral power distributions, and gamma curves to calculate display image radiance. For LCD displays, the...

Clear daytime skies persistently display a subtle local maximum of radiance near the astronomical horizon. Spectroradiometry and digital image analysis confirm this maximum's reality, and they show that its angular width and elevation vary with solar elevation, azimuth relative to the Sun, and aerosol optical depth. Many existing models of atmospheric scattering do not generate this near-horizo...

The long-term goal of the CoBOP program, of which this project is a part, is to gain a better understanding of the sources, nature, and variability of upwelling radiance in shallow water. This will include both magnitude and spectral characteristics of the radiance. An additional goal is to understand the relationship of coral fluorescence to environmental stress and the possibility for using i...

We consider the problem of estimating the shape and radiance of an object from a calibrated set of views under the assumption that the reflectance of the object is non-Lambertian. Unlike traditional stereo, we do not solve the correspondence problem by comparing image-to-image. Instead, we exploit a rank constraint on the radiance tensor field of the surface in space, and use it to define a dis...
