Blur image algorithm
WebFor a portraiture project, photographer Andres Gonzalez recalls using a Gaussian filter to create a surreal effect. In Adobe 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 focused. WebJan 25, 2024 · This is, in essence, how Gaussian blur works. TLDR: A Gaussian blur is applied by convolving the image with a Gaussian function. In English, this means that we’ll take the Gaussian function and we’ll generate an n x m matrix. Using this matrix and the height of the Gaussian distribution at that pixel location, we’ll compute new RGB values ...
