The expansion in Gaussian derivatives can therefore be used to develop a simple and efficient deconvolution method for images which have been convolved with a Gaussian filter. We consider both one- and two-dimensional problems, and give a discussion of the error caused by truncation of the ...
In Gaussian Blur operation, the image is convolved with a Gaussian filter instead of the box filter. The Gaussian filter is a low-pass filter that removes the high-frequency components are reduced.You can perform this operation on an image using the Gaussianblur() method of the imgproc class...

The two kernels are convolved with the original image to measure an approximation of the derivatives. Even if the markers in the background are not well distributed, the barriers in the elevation map are high enough for these markers to flood the entire background. After that, we remove the...
Gaussian process regression is a way to undertake non-parametric regression with Gaussian processes. The key idea is that, rather than postulating a parametric form for the function f(x,θ) and estimating the parameters θ (as in parametric regression), we instead assume that the function f(x...

We use Bayesian methods to infer an unobserved function that is convolved with a known kernel. Our method is based on the assumption that the function of interest is a Gaussian process and, assuming a particular correlation structure, the resulting convolution is also a Gaussian process. This ...
The main difference with respect to the literature is that the expansion is done after extracting the Gaussian kernels, i.e., we expand only the function that is convolved with the Gaussian kernels. This approach yields particularly interesting results when the GΓ2 kernel is used, given that ...
A Gaussian blur approximation is applied to an image by repeated down-sampling operations followed by an up-sample operation. By using a truncated Gaussian filter as the down-sample
