Struct Legacy_MultiTrackerTLD 

pub struct Legacy_MultiTrackerTLD { /* private fields */ }

Multi Object %Tracker for TLD.

TLD is a novel tracking framework that explicitly decomposes the long-term tracking task into tracking, learning and detection.

The tracker follows the object from frame to frame. The detector localizes all appearances that have been observed so far and corrects the tracker if necessary. The learning estimates detector’s errors and updates it to avoid these errors in the future. The implementation is based on TLD .

The Median Flow algorithm (see cv::TrackerMedianFlow) was chosen as a tracking component in this implementation, following authors. The tracker is supposed to be able to handle rapid motions, partial occlusions, object absence etc.

impl Legacy_MultiTrackerTLDTrait for Legacy_MultiTrackerTLD

fn as_raw_mut_Legacy_MultiTrackerTLD(&mut self) -> *mut c_void

fn update_opt(&mut self, image: &impl ToInputArray) -> Result<bool>

Update all trackers from the tracking-list, find a new most likely bounding boxes for the targets by optimized update method using some techniques to speedup calculations specifically for MO TLD. The only limitation is that all target bounding boxes should have approximately same aspect ratios. Speed boost is around 20%
