Finding subtle logos - tone on tone
Posted: Sat Apr 18, 2009 10:28 pm
Hi all,
First of all I have to say that I love using Comskip, it works great for most shows, and in most situations.
However, there are some situations where it can be quite challenging to find logo's.
In Canada, our logos tend to be quite small <5%, and quite often they change or are VERY subtle, in 24 there is a tone-on-tone logo, that can be difficult to detect using standard settings, I have found that making chages to two setting, seems to help a fair deal:
edge_level_threshold=x
edge_radius=y
My question is, is it better to decrease edge_level_threshold to find a subtle logo, or increase edge_radius, which method is preferred and would tend to give less false positives?
Also specifically for 24, I have found that setting validate_scenechange=0 help when thee is no logo to be found.
Hopefully someone is having the same issues with logos?
