This paper presents a novel method for real-time homogenous translucent material editing under fixed illumination. We consider the complete analytic BSSRDF model proposed by Jensen et al. [JMLH01], including both multiple scattering and single scattering. Our method allows the user to adjust the analytic parameters of BSSRDF and provides high-quality, real-time rendering feedback. Inspired by r...

A non-parametric high dynamic range (HDR) fusion approach is proposed that works on raw images of singlesensor color imaging devices which incorporate the Bayer pattern. Thereby the non-linear opto-electronic conversion function (OECF) is recovered before color demosaicing, so that interpolation artifacts do not affect the photometric calibration. Graph-based segmentation greedily clusters the ...

[1] The spectrally resolved infrared radiances observed by AIRS provide a strict and insightful test for general circulation models (GCMs). We compare the clearand totalsky spectra simulated from the Geophysical Fluid Dynamics Laboratory GCM using a high resolution radiation code with the AIRS observations. After ensuring consistency in the sampling of the observed and simulated spectra and a p...

A method is presented that fuses multiple differently exposed images of the same static real-world scene into one single high dynamic range radiance map. Firstly, the response function of the imaging device, that maps irradiating light at the imaging sensor to gray values, is recovered. The mapping is usually not linear for 8-bit images. This nonlinearity affects image processing algorithms tha...

In recent work radiance function properties and discontinuity meshing have been used to construct high quality interpolants representing radiance. Such approaches do not consider the combined effect of multiple sources and thus perform unnecessary discontinuity meshing calculations and often construct interpolants with too fine subdivision. In this research we present an extended structured sam...

A technique for the assimilation of Special Sensor Microwave Imager (SSM/I) data in the National Centers for Environmental Prediction’s (NCEP’s) global data assimilation and forecast system is described. Because the radiative transfer (RT) model used here does not yet allow for cloud/rain effects, it is crucial to properly identify and exclude (or correct) cloud/rain-contaminated radiances usin...

Charge-Coupled Device (CCD) cameras are widely used imaging sensors in computer vision systems. Many photometric algorithms, such as shape from shading, color constancy, and photometric stereo, implicitly assume that the image intensity is proportional to scene radiance. The actual image measurements deviate significantly from this assumption since the transformation from scene radiance to imag...

Human visual system is capable to capture details in dark and bright areas at the same time despite the dynamic range of the scene. Digital cameras, however, have a limited dynamic range, therefore only capturing dark or bright areas in a single shot. Considering that, Mann and Picard [6] presented a method for the creation of high dynamic range (HDR) radiance map by exposure fusion of a stack ...

Radiance spectroscopy was applied to the interstitial detection of localized inclusions containing Au nanocages or nanorods with various concentrations embedded in porcine muscle phantoms. The radiance was quantified using a perturbation approach, which enabled the separation of contributions from the porcine phantom and the localized inclusion, with the inclusion serving as a perturbation prob...
