Robust Visual Correlation Tracking

Algorithm 1

Proposed tracking algorithm.
Input: The th frame video sequence , Initial target position and scale .
Output: Detected target position and scale .
Repeat:
Crop out the searching region in frame according to and , and extract the sample ;
//Position Detection:
() Compute the response with , and using (12);
() Find the target position which maximizes .
//Scale Prediction:
() Extract a sample from at and ;
() Compute the response with , and using (16);
() Find the target scale which maximizes .
//Model Online Update:
() Extract samples and from at and ;
() Update using (13), (14) and update using (9);
() Update using (13), (14) and update using (9).
Until the End of the Video Sequence
