any suggestion for more accurate combed detection?

[Valeron]

Source Type: Anime
i'm using iscombed() to find out the wrong field match after telecide, but when the source fed to iscombed without filtered/denoise/resize and setting a low threshold, the result seems confused a lot. too many non-combed frame was reported as combed and several very combed frame can't be caught even at threshold 15!

is there a path prooved to make the detection more accurate?

PS: i c to test all the filters is very time consumming so i would like to ask for help here....

hehe... there's slightly more accurate methods than iscombed, but they tend to give just as many false positives, just on different frames.

comb detection is something i'm always having a poke at, so watch this forum if i come up with something that works better than current methods...

Well, sometimes I had better luck running a decomb filter after doing a few other filters. This at times makes the decomb filter decide whether or not a frame is combed with less effort.

Example:

AVISource("blarg.avi")
# a few cleaner filters here
DecombFilter()


Example #2:
Avisource("blarg.avi")
SeparateFields()
# a few cleaner filters here
Weave()
DecombFilter()


Note: DecombFilter is probably not actual filter. Just replace that function with your favourite decomber.
