avs2.5 usage for "declicking" of the video...[ see this thread on doom9 forum for explanation of this filter, and this filter in context of VHS drop-outs on VDub forum ] :

every image is cca.85kB


few notes;
"wdr-xxxx.jpg"=>768x576(mjpeg)->kerneldeinterlaced->bicubicresize(512,384,0,0.75)

"wdr-xxxx-deint-declick.jpg"=>768x576(mjpeg)->kerneldeinterlaced->declick->bicubicresize

"wdr-xxxx-resize-declick.jpg"=>768x576(mjpeg)->kerneldeinterlaced->bicubicresize->declick


obviously much more effective when applied after downsizing (as opposed to applying it immediately after the deinterlacing)
last segment of video (from "wdr-0056") gave it some trouble;you'll notice how faces are too much blurred (this was so during the complete scene) as if the filter thought people's faces were dots too....(you can't argue that there are some "dots" on people's faces when watched from a distance;eyes,nose,mouth...but those sholdn't be removed.....)

so the main problem is the blur in the areas where there shouldn't be any........
(as it's hard to differentiate real "clicks" from the image content that looks like clicks (small "dotty" details in the image)


[test re-done;old one was confusing,more appropriate end resolutions used now,clearer explanations on the image naming,more images......
copyleft 26.08.2003. by i4004:everyone is invited to make some more tests of this filter which might prove me wrong.........in fact i would love that to happen.........i would also love to test K.Atkinson's simillar filter and compare these two....let's hope he'll get that thing working...soon....(i have a movie on vhs that needs it badly)]
