Ask for dataset for training

[trinamntn08]

Hi,
I'm doing a project similar to you to detect principal lines and i found that your project is really interesting. But i have one question concerning the detecting principal lines on a palm using CNN model.
Can you please share how you define the output data for training please ? In fact, i have a dataset for input, but i don't know how to define the output (normally, they are 3 principals lines), but how to define them for training model , please?

Thanks in advance,
