I don't think it is a weighted average. I believe you have to divide at some point for averaging to be going on. Convolutions just add up the neighborhood based on the kernel, and output their sum.
- userbinator 9y agoIt still gets across most of the point of how it works. As for dividing, that's what the Divisor option is for. To quote the article: "The result of previous calculation will be divided by this divisor. You will hardly use 1, which lets result unchanged, and 9 or 25 according to matrix size, which gives the average of pixel values."
