Example 1: Using fspecial() Function The fspecial() function is used to create a Gaussian filter, and then the Laplacian of this Gaussian is computed to create the LoG filter. However, the Laplacian filter expects the Gaussian filter to be of type double. ...
photographer Andres Gonzalez recalls using a Gaussian filter to create a surreal effect. InAdobe Photoshop, he added a duplicate layer over the original image and applied a Gaussian blur to that. Then, he says, “I went in with an eraser and erased the blur in places that I wanted to be...
It should be noted that the Gaussian filter is not applicable for all functional aspects of a surface, for example in contact phenomena, where the upper envelopeof the surface is more relevant. A standardised framework for filters has been established, which gives a mathematical foundation for fil...

In mahotas, to perform gaussian filtering with different order, we pass any value other than 0 as theorderparameter to the gaussian_filter() function. Example In the example mentioned below, we are applying Gaussian filtering on an image with different orders. ...
In this OpenCV tutorial, we will learn how to apply Gaussian filter for image smoothing or blurring using OpenCV Python with cv2.GaussianBlur() function.
In this work, we present a novel method for approximating a normal distribution with a weighted sum of normal distributions. The approximation is used for splitting normally distributed components in a Gaussian mixture filter, such that components have s
Gaussian blur is a widely used filter in Photoshop that helps photographers and graphic designers achieve a variety of visual effects. It is particularly useful in reducing noise, simulating depth-of-field, and softening imperfections in an image. By utilizing the Gaussian function, this filter crea...
