TrackerCSRT

trackingclassOpenCV 5.0.0

import { TrackerCSRT } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

Explore visually: CSRT tracking →

Track an initialized object with correlation filters weighted by channel and spatial reliability.

VISUAL WALKTHROUGHMotion

REFERENCE INPUTTarget moves in the next frame

The previous position is a starting estimate, not the new target location.

→

RESULTUpdate the target box

Update position, scale and reliable appearance support.

Illustrative example. The stages explain the method; they are not a live OpenCV execution.

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Tracker.

Tracking is an important issue for many computer vision applications in real world scenario. The development in this area is very fragmented and this API is an interface useful for plug several algorithms and compare them. the CSRT tracker

The implementation is based on [Lukezic_IJCV2018] Discriminative Correlation Filter with Channel and Spatial Reliability

Constructors and members

static create

Create CSRT tracker instance

create(parameters: TrackerCSRT_Params): TrackerCSRT | null;

2 available overloads

create(): TrackerCSRT | null;

create(parameters: TrackerCSRT_Params): TrackerCSRT | null;

parameters

CSRT parameters TrackerCSRT::Params

Returns

The TrackerCSRT | null result.

Upstream declaration ↗

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

setInitialMask

void init(InputArray image, const Rect& boundingBox) CV_OVERRIDE; bool update(InputArray image, CV_OUT Rect& boundingBox) CV_OVERRIDE;

setInitialMask(mask: Mat): void;

mask

mask argument (Mat).
