questions regarding annotation file in SDD dataset

[qitop]

Hi, I have some confusions regarding the columns in annotation files. if you could answer that

1-)you have provided the reference images along with annotations. That means that all the trajectories are happing in still images right?

2-)What does it mean by the same path considering the trajectories Track ID. All rows with the same ID belong to the same path.

3-)"annotation is outside" means if the bounding box gets outside the image? lost. If 1, the annotation is outside of the view screen.

4-) I couldn't understand this line generated. If 1, the annotation was automatically interpolated.
