Abstract
Mean-Shift algorithm with fixed bandwidth often fails in tracking an object that moves too fast or owns a dramatic change in scale.To solve the problem,a new Mean-Shift tracking algorithm based on adaptive bandwidth was proposed.Mean-Shift vector was used to predict the center position and automatically modulate the size of tracking window that fixed the object inside the window and gained accurate object position.After confirming the position,a Bhattacharyya coefficient based dichotomy was adopted to select the pantograph ratio automatically,and a tracking window adapted to the scale of object was obtained.The experimental results prove the algorithm's capability in locating object's position and scale.
