Prepare Dataset

mRI-Walking:

python tools/create_data.py mri --root-path /parent/of/dataset_release/folder --out-dir data/mri

Run online reading with visualization

python tools/run_app.py configs/apps/read_and_vis.py

Run offline tracking (optional visualization)

python tools/run_app.py configs/apps/tracking_mri-walking_rkf.py

Tracking details

All tracker threads consume a signal with the following format:

data = np.stack([
    det_obj["x"], 
    det_obj["y"], 
    det_obj["z"], 
    det_obj["doppler"], 
    det_obj["peakVal"]
], axis=-1)

Tracker Output Formats

Tracker Type	Output Format	Description	Example Trackers
Cartesian Tracker	[x, y, z]	Centroid in Cartesian coordinates	AsteriosTracker, GTracker
Polar Tracker	[r, theta, r']	Centroid in polar/radial coordinates	RKFTracker

• The output is always a list of nd.arrays, each representing the centroid of a detected object.
