### Traincascade parameters -> -numPos and -numNeg

Hi , I' m tring to understand what -numNeg and -numPos are , indeed i read some Q&A (here for exemple) which helped me a lot ,but I m still confuse conserning -numNeg, infact I read from @StevenPuttemans ( here) that -numNeg is not the exact number of my Negative images:

I get the impression you are mixing up the concept of negative images (which is gathered manually) and negative windows (which are indicated by -numNeg and which are automatically retrieved from the negative set you supplied at model size).

So i now know was -numNeg is not but I can't get what -numNeg is ^^

Looking foreward to your andswers, Regards , Luc
