Unknown frame id for the submission of future hand prediction challenge

[masashi-hatano]

According to the submission guidelines of future hand prediction challenge, the submission format should be a .json file with following format:

  {"ClipId1_FrameId1": 
  [p3_left_hand_x, p3_left_hand_y, p3_right_hand_x, p3_right_hand_y,
  p2_left_hand_x, p2_left_hand_y, p2_right_hand_x, p2_right_hand_y,
  p1_left_hand_x, p1_left_hand_y, p1_right_hand_x, p1_right_hand_y, 
  p_left_hand_x, p_left_hand_y, p_right_hand_x, p_right_hand_y, 
  c_left_hand_x, c_left_hand_y, c_right_hand_x, c_right_hand_y], 

  "ClipId1_FrameId2": 
  [p3_left_hand_x, p3_left_hand_y, p3_right_hand_x, p3_right_hand_y,
  p2_left_hand_x, p2_left_hand_y, p2_right_hand_x, p2_right_hand_y,
  p1_left_hand_x, p1_left_hand_y, p1_right_hand_x, p1_right_hand_y, 
  p_left_hand_x, p_left_hand_y, p_right_hand_x, p_right_hand_y, 
  c_left_hand_x, c_left_hand_y, c_right_hand_x, c_right_hand_y], 
  
  ...
  }

However, we only know clip_id, clip_uid, and, video_uid for test data:

{
  "version": "1",
  "date": "220217",
  "description": "FHO Hands & Objects",
  "manifest": "s3://ego4d-consortium-sharing/public/v1/full_scale/manifest.csv",
  "split": "test",
  "clips": [
    {
      "clip_id": 3,
      "clip_uid": "de4a85e5-1809-4547-ae11-9161aa9fdbe9",
      "video_uid": "31ea56e6-7a99-4b91-b74b-3b1e6de05e99"
    },
    {
      "clip_id": 2056,
      "clip_uid": "83acc738-4435-451d-a38f-2a3a6cd85879",
      "video_uid": "4ce9f93b-f44c-46fe-9050-3452d2f39abb"
    },
    {
      "clip_id": 10,
      "clip_uid": "bd5e0084-7bf1-4e34-abba-cc3f6a370213",
      "video_uid": "cde41c4f-50d1-4910-9f2a-4c7b6987df92"
    },
...
}

Then, I would like to know how can we know which frame is corresponding to the last observable frame (one frame before pre45 frame)?

Hi @masashi-hatano thank you for the comment, we added the pre45 frame id information back in our test annotation now, please check it out!

[masashi-hatano]

Hello @VJWQ , thank you for the reply, could you specify the location of the new test annotation file?
I redownloaded annotations from S3 backet of ego4d, but it seems that fho_hands_test_unannotated.json file has not been changed.

[VJWQ]

Hi @masashi-hatano seems that our people have not updated the new annotation yet, please allow some time for us to sync things up. Maybe come back tomorrow, I believe both scripts and annotations should be updated by then.

Excuse me, has the test file been updated?
