Hello, now I am trying to understand СascadeСlassifier (Viola - Jones) algorithm. Is it possible to compute probability of detection? Can I get it from reject and weight levels returned from СascadeСlassifier.detectMultiScale()?

AFAIK, there is no probability of detection computed internaly because this is not how the algorithm works. You can however estimate an arbitrary detection score based on the reject level, the level weight is undocumented and I don't believe it can have a usable meaning across the levels.

Unfortunately, I could not retrieve the weights myself (see my question here).
