Efficient Storage and Importance Sampling for Fluorescent Reflectance

چکیده
We propose a technique for efficient storage and importance sampling of fluorescent spectral data. Fluorescence is fully described by re-radiation matrix, which given input wavelength indicates how much energy re-emitted at other wavelengths. However, such representation has considerable memory footprint. To significantly reduce requirements, we the use Gaussian mixture models matrices. Instead full-resolution work with set parameters that also allow direct sampling. Furthermore, if accuracy concern, matrix can be used jointly provided mixture. In this paper, present our pipeline bispectral data provide its extensive evaluation on large measurements. show method robust colour accurate even comparably minor requirements it seamlessly integrated into standard Monte Carlo path tracer.

Efficient Importance Sampling for Binary Contingency Tables
Importance sampling has been reported to produce algorithms with excellent empirical performance in counting problems. However, the theoretical support for its efficiency in these applications has been very limited. In this paper, we propose a methodology that can be used to design efficient importance sampling algorithms for counting and test their efficiency rigorously. We apply our technique...
متن کاملEfficient High-Dimensional Importance Sampling
The paper describes a simple, generic and yet highly accurate Efficient Importance Sampling (EIS) Monte Carlo (MC) procedure for the evaluation of high-dimensional numerical integrals. EIS is based upon a sequence of auxiliary weighted regressions which actually are linear under appropriate conditions. It can be used to evaluate likelihood functions and byproducts thereof, such as ML estimators...
متن کاملEfficient Post-processing with Importance Sampling
Introduction Texture filtering is a critical part in many rendering and post-processing methods. If we do it naively, the fragment shader needs to access the texture memory many times to fetch values in the neighborhood of the processed texel. This article presents an efficient filtering algorithm that minimizes the number of texture fetches. The algorithm is based on importance sampling and al...
متن کاملImproving MCMC, using efficient importance sampling
This paper develops a systematic Markov Chain Monte Carlo (MCMC) framework based upon E cient Importance Sampling (EIS) which can be used for the analysis of a wide range of econometric models involving integrals without an analytical solution. EIS is a simple, generic and yet accurate Monte-Carlo integration procedure based on sampling densities which are chosen to be global approximations to ...
