Hi and here is a summary for new updates in this PR

In this PR, changlin add MOT configuration, with following fields:

  • carema_id
  • frame_id
  • conf
  • ignore
  • visibility/ratio

Assumptions: By now the given data has no occlusion issues. And all labeling are visible.

Considering that we may need inference result of detection, set conf=1 to match inference and set ignore = 0 and visibility_ratio = 1 to use all annotations

carema_id and frame_id are extracted automatically from folder and filename

In MTMC we may need to consider how multiple caremas associate together.
So we split dataset after merging all annotations and image.
This requires a refactor of the current annotation structures.

Tree structure for MOT:
-------test-folder
--------------camera_id1
---------------------gt
----------------------------coco.json
---------------------img
----------------------------0001.jpg
----------------------------0002.jpg
--------------camera_id2
---------------------gt
----------------------------coco.json
---------------------img
----------------------------0001.jpg
----------------------------0002.jpg
