Certain images, including this one, are anti-aliased very sharply, but also have ringing. Medians share properties with surface blur type effects, and when you filter over these sharp ringed edges, you get the same aliasing behavior. The "blurrier" variant should cause less of this behavior ... chronergy of news

"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.
