Web8 de jan. de 2013 · It actually removes high frequency content (eg: noise, edges) from the image. So edges are blurred a little bit in this operation (there are also blurring techniques which don't blur the edges). OpenCV provides four main types of blurring techniques. 1. Averaging. This is done by convolving an image with a normalized box filter.
