Wavelets for Computer Graphics: A Primer Part 1 Introduction Wavelets are a mathematical tool for hierarchically decomposing functions. They allow a function to be described in terms of a coarse overall ... EJ Stollnitz,TD Derose,DH Salesin - 《IEEE Computer Graphics & Applications》 被引量:...
For example, shown below are two frames from astaticcamera. Comparing corresponding pixels in frame1 and frame2 (for each x,y), you should be able to assess pixels that have “not changed” and hence can serve as “green screen” pixels. Also, pixels that have changed and hence are fore...
Using wavelets in computer graphics A new technique in the creation of the stack frame of a function has been developed with the capability of storing dynamic variables in the same area as local variables. This innovation permits the writing of an array declaration in C/C+... D Ruch,J Shu...
实践中,最好选个实际的water wave的波谱,作者抄的这个paper里的Empirical Directional Wave Spectra for Computer Graphics 具体是啥我之后看看他代码里咋写的 然后事实上用很稀疏的Grid就行了,theta用了16个Sample,再高也提升不了质量,K的话只用了1个Sample, X是4096*4096的,1个Grid代表1m ...
To construct discrete wavelets for representing functions on a sphere, Schröder and Sweldens proposed the lifting scheme and validated its effectiveness [36]. Although spherical wavelets based on the lifting scheme have been widely applied to computer graphics, to the best of the authors’ ...
In this paper, we present a novel method for texture mapping of closed surfaces. Our method is based on the technique of optimal mass transport (also known... A Dominitz,A Tannenbaum - 《IEEE Transactions on Visualization & Computer Graphics》 被引量: 78发表: 2010年 Perceptual Fidelity Measu...
In many application fields, ranging from astrophysics and geophysics to neuroscience, computer vision, and computer graphics, data to be analyzed are defined as functions on the sphere. In all these situations, there are compelling reasons to design dedicated data analysis tools that are adapted to...
International Journal of Wavelets, Multiresolution and Information Processing (hereafter referred to as IJWMIP) is a bi-monthly publication for theoretical and applied papers on the current state-of-the-art results of wavelet analysis, multiresolution and information processing. Papers related to the ...
Wavelets have been used in a broad range of applications such as image processing, computer graphics and numerical analysis. The lifting scheme provides an... J Maes,A Bultheel - 《Applied Numerical Mathematics》 被引量: 12发表: 2008年 加载更多来源...
