Hello Everyone, I'm new in to OpenCv and Cascade training. How can I calculate -numstages -numpos -numneg. My .vec file contains 6 positive Samples. And i have 129 negative Images. Can you help me with the calculation?

I don't find my problem. I've now selected some more positives (36). But the training stops after the first stage. Even if i just do it with -numStages 2 -numPos 1 -numNeg 10. But why? After the calculation like in the link you posted, there must be enough images.

3600 positives would be realistic. (and give like 80% of what you have to numPos)
