+### Ground Truth Format (MOTChallenge) for `MTMC_Tracking_2024`
+Annotations are provided in the following text format per line:
+
+```
+<camera_id> <obj_id> <frame_id> <xmin> <ymin> <width> <height> <xworld> <yworld>
+```
+
+- `<camera_id>`: Numeric identifier for the camera.
+- `<obj_id>`: Consistent numeric identifier for each object across cameras.
+- `<frame_id>`: Frame index starting from 0.
+- `<xmin> <ymin> <width> <height>`: Axis-aligned bounding box coordinates in pixels (top-left origin).
+- `<xworld> <yworld>`: Global coordinates (projected bottom points of objects) based on provided camera matrices.
+
+The video file and calibration (camera matrix and homography) are provided for each camera view.
