Basic steps of tracing method

Tracking is an important technology in the field of computer vision, which is mainly used to track the motion trajectory of targets in video or image sequences. The following are the basic steps of tracing method:

1. Determine the position and range of the target in the first frame of image or video.

2. Extract features from the detected target area, such as color, shape, texture, etc.

3. Match the target features of the current frame with those of the previous frame to determine the position and trajectory of the target in the continuous frames.

4. According to the matched target features, estimate the state of the target in the current frame, such as speed and direction.

5. Correct the error of the tracking result and improve the tracking accuracy.

6. Repeat the steps of target detection, feature extraction, target matching, state estimation and error correction in subsequent frames until the tracking task is completed.
