## Detailed Description

The TrackerParams struct stores parameters of TrackerByMatching.

## Constructor & Destructor Documentation

## ◆ TrackerParams()

cv::tbm::TrackerParams::TrackerParams | ( |  | ) |

Default constructor.

## Member Data Documentation

## ◆ aff_thr_fast

float cv::tbm::TrackerParams::aff_thr_fast

Affinity threshold which is used to determine if tracklet and detection should be combined (fast descriptor is used).

## ◆ aff_thr_strong

float cv::tbm::TrackerParams::aff_thr_strong

Affinity threshold which is used to determine if tracklet and detection should be combined(strong descriptor is used).

## ◆ bbox_aspect_ratios_range

cv::Vec2f cv::tbm::TrackerParams::bbox_aspect_ratios_range

Bounding box aspect ratios range.

## ◆ bbox_heights_range

cv::Vec2f cv::tbm::TrackerParams::bbox_heights_range

Bounding box heights range.

## ◆ drop_forgotten_tracks

bool cv::tbm::TrackerParams::drop_forgotten_tracks

Drop forgotten tracks. If it's enabled it disables an ability to get detection log.

## ◆ forget_delay

size_t cv::tbm::TrackerParams::forget_delay

Forget about track if the last bounding box in track was detected more than specified number of frames ago.

## ◆ max_num_objects_in_track

int cv::tbm::TrackerParams::max_num_objects_in_track

The number of objects in track is restricted by this parameter. If it is negative or zero, the max number of objects in track is not restricted.

## ◆ min_det_conf

float cv::tbm::TrackerParams::min_det_conf

Min confidence of detection.

## ◆ min_track_duration

size_t cv::tbm::TrackerParams::min_track_duration

Min track duration in milliseconds.

## ◆ motion_affinity_w

float cv::tbm::TrackerParams::motion_affinity_w

Motion affinity weight.

## ◆ predict

int cv::tbm::TrackerParams::predict

How many frames are used to predict bounding box in case

## ◆ reid_thr

float cv::tbm::TrackerParams::reid_thr

Affinity threshold for re-identification.

## ◆ shape_affinity_w

float cv::tbm::TrackerParams::shape_affinity_w

Shape affinity weight.

## ◆ strong_affinity_thr

float cv::tbm::TrackerParams::strong_affinity_thr

of lost track.

If 'fast' confidence is greater than this threshold then 'strong' Re-ID approach is used.

## ◆ time_affinity_w

float cv::tbm::TrackerParams::time_affinity_w

Time affinity weight.
