Web8 de jan. de 2013 · OpenCV provides four main types of blurring techniques. 1. Averaging This is done by convolving an image with a normalized box filter. It simply takes the average of all the pixels under the kernel area and replaces the central element. This is done by the function cv.blur () or cv.boxFilter ().

WebIn image processing, a convolution kernel is a 2D matrix that is used to filter images. Also known as a convolution matrix, a convolution kernel is typically a square, MxN matrix, where both M and N are odd integers (e.g. 3×3, 5×5, 7×7 etc.). See the 3×3 example matrix given below.
