To improve the robust and processing speed of the Tracking-Learning-Detection(TLD), the robust and fast TLD tracker is proposed.Replacing with the forward-backward error predictor, The two powerful failure predictors, including the neighbourhood consistency predictor and the markov predictor in the tracker, are used to reduce the computational cost and improve the precise.The RANSAC algorithm is added to estimate the global motion model and improve the success rate of tracking.Replacing with P-N learning in sample learning procedure, We use a novel online weighted P-N learning which integrates the sample importance into an efficient online learning procedure to alleviate drift to some extent.Experimental results on various benchmark video sequences demonstrate the superior performance of the proposed algorithm to state-of-the-art tracking algorithms in robustness, stability and efficiency.
