I tried to train with traincascade until the 8th stage. I know, it is few. Now that's why I want to reteach the classifier until 12th stage.

My first question is that if I do not modify other parameters than the maximum number of stages, will the first 8 stage change? I compared the output results, but at the time I did not noticed any difference (except precalculation time).

If no, my second question is that, can I reteach only continuing from the 9th (number 8) stage to get a working cascade? And if I can reteach, how? I could not find any parameter related to this.

I know, there was more post related to this issue, but I couldn't get clear answer to my question.

Thanks!

Answers to your questions

  1. No it will not affect the previous stages if ONLY the number of stages changes.
  2. Yes you can, use the same cascade folder, but remove the cascade.xml file. Leave the stage0 - stage7 xml files there and it will just continue training.
