What is the "f" that is concatenated to the line feature vector x? #42

Hi, I am trying to extract lcnn line features given the line segments detected by lsd, but I am stuck here:

https://github.com/zhou13/lcnn/blob/290b457ec54f2aeb8e7de88c6837747ebc5aa168/lcnn/models/line_vectorizer.py#L95 x seems to be the feature vector, after the max-pooling, you concatenate the x and f before the fully connected layer. What is the f here?

In my modification, the size of x equals to the number of lsd lines, which is different from the size of f. Any suggestions on how to modify the f?

f is represents hardcoded feature. By default, it is just a zero vector.
