WebApr 12, 2024 · Linear image filtering. The simplest filter is a point operator. Each pixel value is multiplied by a scalar value. This operation can be written as follows: Here: The input image is F and the value of pixel at (i,j) is denoted as f (i,j) The output image is G and the value of pixel at (i,j) is denoted as g (i,j) K is scalar constant. WebOpenCV provides mainly four types of blurring techniques. 1. Averaging ¶. This is done by convolving the image with a normalized box filter.
