See.dll where to find?

[Neoze]

in some post Marc FD talk about see.dll

http://forum.doom9.org/showthread.php?s=&threadid=29359&highlight=see.dll

To test/compare filters i use See.dll in
Subtract(a,b).See(0,min,max).levels(min,1,max,0,255)
combinaisons :
- 128-130 for low-freq noise,
- 131,140 for med-freq noise and
- 141,160 for high-freq noise.
The thing i prefer is to use See(5) (HSL:S)
and See(7) (HSL:H) It acts like a revelator
and show you things you would never suspect
(like the monstruous ugly quantisation from
DivX 5 on chroma...)

But I could'nt find it? :confused:
Thank you for your help.

Use the built in "compare" or "subtract" function. Compare provides more information, and Marc's graph.

Thanks you for your response.
I tried compare. But, it no so easy to interpret. I Still use stackvertical to see de difference between filtered and unfiltered frame.

hopefully this helps

After a lot of tests. Each filter x n pictures x parameters.
I have found a method to help in this task.

The first idea is to chose pertinents pictures, and to create an avi with this pictures.
Easy with the ImageSequence Dll.

The second idea is to interleave filtered and unfiltered picture so that it will be easy to change frame an see the difference.

And last to have the focus to the main picture dégradation (or cleaning) I use the D. Graft dup dll.
http://shelob.mordor.net/dgraft/dup/dup.html
Then you have a value who speframe difference

@ D. Graft: it would be very convenient if you could highlight more areas (5) with differents colors for the strongest different area to the smallest different area.

I will make a other script to mesure temporal filter.

I didn't validate your attachment because the zip was very large and, worse, it was spanned across multiple posts. For this kind of thing it is better to put it on a website and post the URL. Thank you.

Sorry,
You will find the file (800k) in this thread
http://forum.media-video.com/viewtopic.php?t=8523


======here the script =================
s=ImageSequence("Image%d.jpg",0,7,25)
s=s.converttoyuy2()

d=s.Convolution3d(0,8,8,8,8,3,0)

i1=trim(s,1,1)
i2=trim(s,2,2)
i3=trim(s,3,3)
i4=trim(s,4,4)
i5=trim(s,5,5)
i6=trim(s,6,6)

j1=trim(d,1,1)
j2=trim(d,2,2)
j3=trim(d,3,3)
j4=trim(d,4,4)
j5=trim(d,5,5)
j6=trim(d,6,6)

video=i1+j1+i2+j2+i3+j3+i4+j4+i5+j5+i6+j6
dup(video,threshold=5,show=true,debug=true)
=======================================================

If you want to see what the filter is removing replace the last line with:

Subtract(s,d).Levels(120,1,130,0,255)

What did you think about the modification in Dup.dll so that it highlight more area and help find the change beetwen two pictures.

@Neoze

Your Dup() suggestion sounds useful. Would you mind adding your request to the main Dup() thread so I have all the requests in one place? I plan to start working on Dup() enhancements very soon. Thank you.

[Neoze]

@neuron2
The request is posted just now.
