Some question in paper

[ponyyangzeng]

1. Does 1 query be responsible for 1 instance lane?
2. How to predict all points of a lane in parallel?
3. In key points detection stage, is output shape like (N, k, 2), (N, _clsnum), where N is _numquery, k is _num_keypoint ?
4. After hungarian matching, will only matched query be used for polyline generation?

[Mrmoore98]

A1: one element query corresponding to one instance, and one element query has three keypoint query which correspond to a keypoint. A2: polyline generator autoregressively generate each point of the lane, but we can decode the all lanes in parallel. A3: Yes A4: Yes
