WebbIn 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. (1) A 3×3 2D convolution kernel. Webb8 jan. 2013 · A 5x5 averaging filter kernel will look like the below: The operation works like this: keep this kernel above a pixel, add all the 25 pixels below this kernel, take the average, and replace the central pixel with the new average value. This operation is continued for all the pixels in the image. Try this code and check the result:

You can see that when applying it to images, where a radius of 1 ( 3x3 matrix) is noisy and a radius of 2 ( 5x5 matrix) or greater is not very useful. So called "unsharp" filters first apply a Gaussian filter, effectively blurring the image a bit, to wipe ... ear sore and itchy
