ITWVTSP uses ITWPCA for computing incrementally a robust low dimensional subspace representation (model) of the tracked object. The robustness is based on the capacity of weighting the contribution of each single sample to the subspace generation to reduce the impact of bad quality samples, reducing the risk of model drift. Furthermore, ITWVTSP can exploit the a priori knowledge about important regions of a tracked object. This is done by penalizing the tracking error on some predefined regions of the tracked object, which increases the accuracy of tracking. Several tests are performed on several challenging video sequences, showing the robustness and accuracy of the proposed algorithm, as well as its superiority with respect to state-of-the-art techniques. 000195204 6531_ $$aLTS5 000195204 6531_ $$aOnline learning 000195204 6531_ $$aprincipal component analysis (PCA) 000195204 6531_ $$avisual tracking (VT) 000195204 700__ $$0243039$$g172622$$aCruz, Javier 000195204 700__ $$0240563$$g118332$$aBierlaire, Michel 000195204 700__ $$0240323$$g115534$$aThiran, Jean-Philippe 000195204 773__ $$j23$$tIEEE Transactions on Circuits and Systems for Video Technology$$k5$$q898-911 000195204 8564_ $$uhttps://infoscience.epfl.ch/record/195204/files/06471191.pdf$$zPublisher's version$$s1218346$$yPublisher's version 000195204 909C0 $$xU10954$$0252394$$pLTS5 000195204 909C0 $$0252123$$pTRANSP-OR$$xU11418 000195204 909CO $$qGLOBAL_SET$$particle$$pSTI$$pENAC$$ooai:infoscience.tind.io:195204 000195204 917Z8 $$x115534 000195204 917Z8 $$x148230 000195204 937__ $$aEPFL-ARTICLE-195204 000195204 970__ $$aIJ-CruzBierThir13/TRANSP-OR 000195204 973__ $$rREVIEWED$$sPUBLISHED$$aEPFL 000195204 980__ $$aARTICLE
