WebThat's a drawback of denoising with a median filter. 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 ...
