Factoring of Multiple Function Wavelet Production Sampling

چکیده
Importance sampling methods of wavelet products can deal with some direct rendering applications with only two functions. For multiple functions sampling that are more useful in global rendering, we present a wavelet-based factor method to simplify multiple function integral into triple function product issues. Then an optimal wavelet product representation is introduced. Major algorithms with pseudo code are in detail to reduce computation by a strategy for hierarchically sampling a wavelet tree. Key-Words: Monte Carlo Integral; Wavelet Product; Importance Sampling; Dynamic Rendering

Locally Adaptive Products for All-Frequency Relighting
Triple product integrals evaluate the shading at a point by factoring the reflection equation into incident illumination, visibility, and BRDF. By densely sampling the space of incident directions, this approach is capable of highly accurate rendering scenes lit by high-frequency environment lighting, containing complex materials and featuring intricate shadows. Efficient evaluation of triple p...
متن کاملApproximation Error for Quasi-Interpolators and (Multi-)Wavelet Expansions
We investigate the approximation properties of general polynomial preserving operators that approximate a function into some scaled subspace of L via an appropriate sequence of inner products. In particular, we consider integer shift-invariant approximations such as those provided by splines and wavelets, as well as finite elements and multi-wavelets which use multiple generators. We estimate t...
متن کاملAn overcomplete discrete wavelet transform for video compression
The translated function with any integer multiple of the sampling period is completely represented in the wavelet space by one of the Overcomplete Discrete Wavelet Transform (ODWT ) members. This theoretical result leads to a new motion estimation and motion compensation scheme working in the wavelet transform domain. Our experiments, performed on real image sequences, show high quality and low...

An optimal desirability function method is proposed to optimize multiple responses in multiple production scenarios, simultaneously. In dynamic environments, changes in production requirements in each condition create different production scenarios. Therefore, in multiple production scenarios like producing in several production lines with different technologies in a factory, various fitted r...
