Algorithm of ScaleChanging Object Tracking Based on LogPolar Transformation
A practical tracking system should be equipped with scale adaptation mechanism.To solve the problem of the traditional methods which could not keep up with the scale changing timely and accuratelythe particle filter and an improved Mean Shift method were introduced to locate the centroid of the target.Thenthe correlation coefficient was adopted to map the object and its candidate in the LogPolar Transformation domain to fit the target scale.Experimental results demonstrated that the composite algorithm can select a proper size of tracking window adaptively.Compared with the traditional methodit has a better robustness.
