Created attachment 103526 [details] Part of depth map with visible noise It seems it's impossible to set threshold to 0, that there is always some threshold turned on. I've compared it with PS unsharp mask and it's similar to about 10 (of 255). Please check on attached file, it contains nice noise that shows problem.
