Understanding BoT-SORT in yolov11

[ykn96]

Hello! I see that BoT-SORT is being implemented in the ultralytics library and i wish to get a better understanding of it
In the ultralytics library, i see that there is a BoT-SORT.yaml file which contains

# Ultralytics 🚀 AGPL-3.0 License - https://ultralytics.com/license

# Default Ultralytics settings for BoT-SORT tracker when using mode="track"
# For documentation and examples see https://docs.ultralytics.com/modes/track/
# For BoT-SORT source code see https://github.com/NirAharon/BoT-SORT

tracker_type: botsort # tracker type, ['botsort', 'bytetrack']
track_high_thresh: 0.25 # threshold for the first association
track_low_thresh: 0.1 # threshold for the second association
new_track_thresh: 0.25 # threshold for init new track if the detection does not match any tracks
track_buffer: 30 # buffer to calculate the time when to remove tracks
match_thresh: 0.8 # threshold for matching tracks
fuse_score: True # Whether to fuse confidence scores with the iou distances before matching
# min_box_area: 10  # threshold for min box areas(for tracker evaluation, not used for now)

# BoT-SORT settings
gmc_method: sparseOptFlow # method of global motion compensation
# ReID model related thresh (not supported yet)
proximity_thresh: 0.5
appearance_thresh: 0.25
with_reid: False

May i know What do the values track_high_thresh and track_low_thresh and new_track_thresh and match_thresh mean?
and how are these values computed?
