Object’s scale and rotation estimation using the clustering in tracking methods based on the optic flow calculation
Procedures of scale and rotation estimation of an object using the clustering are proposed. The procedures are oriented to the application in tracking techniques based on sparse optic flow calculation. The new tracking method, which is called FCT (Flow Clustering Tracker) is developed using the mentioned procedures. The obtained results show its ability to achieve the compromise in robustness and accuracy with respect to the existing solutions.
