Parameters

• f – File descriptor (in write mode).

• frame – Frame id corresponding to the RoIs.

• RoIs_id – Array of RoI unique identifiers.

• RoIs_xmin – Array of minimum \(x\) coordinates of the bounding box.

• RoIs_xmax – Array of maximum \(x\) coordinates of the bounding box.

• RoIs_ymin – Array of minimum \(y\) coordinates of the bounding box.

• RoIs_ymax – Array of maximum \(y\) coordinates of the bounding box.

• RoIs_S – Array of RoI surfaces.

• RoIs_Sx – Array of sums of \(x\) properties.

• RoIs_Sy – Array of sums of \(y\) properties.

• RoIs_x – Array of centroids abscissa.

• RoIs_y – Array of centroids ordinate.

• RoIs_magnitude – Array of RoI magnitudes (if NULL, the magnitudes are not shown).

• RoIs_sat_count – Array of RoI saturation counters (if NULL, the saturation counters are not shown).

• n_RoIs – Number of connected-components (= number of RoIs) in the 2D array of labels.

• tracks – Vector of tracks. It enables to match RoIs with corresponding track in the table of RoIs.

• age – 0 if frame is the current frame, 1 if frame is the \(t - 1\) frame. This is mandatory to find the corresponding track (if any).
