How does it work? The "pyramid" is constructed by repeatedly calculating a weighted average of the neighboring pixels of a source image andscalingthe image down. It can be visualized by stacking progressively smaller versions of the image on top of one another. This process creates a pyramid ...
Various methods of image filtering can include processing techniques associated with the Gaussian pyramid. Linear filtering is often used, while images with corrupted data can be processed by using non-linear filters to remove noise, or distortions produced by unwanted data. The Gaussian pyramid techni...

At rendering time, a process calledGaussian rasterizationtransforms each Gaussian particle into the appropriate red, blue and green colored pixels that make up each view. This is related to the rasterization process used to transform raw 3D data in other techniques but using different algorithms. For...
Some statistical models presume the errors to be Gaussian. This enables distributions of functions of normal variables, like the chi-square- and F-distribution, to be used in hypothesis testing. Specifically, in the F-test, the F statistic is composed of a ratio of chi-square distributions, ...
(s), say θ, do not have any interpretation apart from their predictive power.Footnote9Bayesian optimization solves the problem sequentially, by first using existing evidence to construct a surrogate model following a Gaussian process of a joint probability distribution across alternative functions.Foot...
The discovery and development of new drugs is a complex process that involves the simulation of millions of chemical compounds to identify those that have the potential to treat diseases. Traditional methods of drug discovery have been limited by insufficient computational power, but HPC and GPU tech...
A Gaussian mixture model (GMM) is a category of probabilistic model which states that all generated data points are derived from a mixture of a finite Gaussian distributions that has no known parameters. The parameters for Gaussian mixture models are derived either from maximum a posteriori estimati...
