“…A good tracking algorithm needs to be able to track target's scale and rotation changes correctly. Mean Shift algorithm [2,3,4] has applied successfully in the field of target tracking , it has some advantages such as small amount of calculation and good realtime performance, But this algorithm can't track rotating change of the target .For the scale change of target, Comaniciu D et al puts forward the method of plus or minus 10 of the increment to modified the nuclear window width [2,5,20,21]. Although the literature [6,22,23,24] can better meet the target scale changes, it can't make proper adjustment according to target's angle variation.…”
