Blurring image opencv
WebOpenCV Blur (Image Smoothing) Blurring is the commonly used technique for image processing to removing the noise. It is generally used to eliminate the high-frequency content such as noise, edges in the image. The edges are being blurred when we apply blur to the image. The advantages of blurring are the following: WebIn OpenCV, image smoothing (also called blurring) could be done in many ways. In this tutorial, we shall learn using the Gaussian filter for image smoothing. Gaussian filters have the properties of having no overshoot …
