The model surface was formed by superimposing the surfaces "Stochastic fractal", "Particles" and "Gaussian noise". The values of the scaling index were obtained from the dependences of the fluctuation function on the scale, as well as the values of the average mutual informatio...

Many experiments in physics involve searching for a localized excess over background expectations in an observed spectrum. If the background is known and there is Gaussian noise, the amount of excess of successive observations can be quantified by the runs statistic taking care of the look-...
// Denoising using Fields of Experts and the Ceres minimizer. // // Note that for good denoising results the weighting between the data term // and the Fields of Experts term needs to be adjusted. This is discussed // in [1]. This program assumes Gaussian noise. The noise model can ...
In this OpenCV tutorial, we will learn how to apply Gaussian filter for image smoothing or blurring using OpenCV Python with cv2.GaussianBlur() function. Image Smoothing using OpenCV Gaussian Blur As in any other signals, images also can contain different types of noise, especially because of the...
