The edge pixels with probabilities higher than a fixed threshold will be viewed as positive samples. You can find detailed description in Section 3.2 of our paper (Richer Convolutional Features for Edge Detection, CVPR 2017).

Thank you.

When I start fine-tuning, I found my loss values were not normal (at first is non, when I revised lr = 1e-15, it was still a very large value), do you have any idea ?

According to the above loss problem, do you think should I change values of the parameters, like, lr, η
, λ in loss function? Or the momentum and weight decay ?
from rcf.
Basically, I changed lr = 1e-8 from 1e-6, and λ = 1.3 from 1.1, then my fine-tuning based on my training data can be run successfully, even though the loss value started from a large value (213869). After 40000 iterations, the loss value can be reduced to 42709.1.
Meanwhile, I tried the fine-tuned model, and it can achieve acceptable results, but I wonder whether the model is over-fitted. I will confirm it.
