英文摘要： This project is motivated by the recent development trends and hot research topics in several interdisciplinary fields (e.g., signal processing, statistical analysis, machine learning, computer vision, etc.), which typically concentrate on the following aspects: local or global feature representation, nonlinear feature transform, signal compression, classifier construction,information fusion,algorithmic complexity analysis, etc. Furthermore, this project aims to establish an effective object tracking framework based on adaptive feature learning and robust appearance modeling, which pay much attention to the studies of several challenging problems in the aspects of adaptive nonlinear feature learning, hashing-based binary feature analysis, hybrid generative and discriminative statistical model design, joint learning of feature representation and appearance modeling, multi-task discriminative learning, and algorithm-running complexity analysis. Using publicly available video datasets and Internet video data, this project generates the output pf a robust object tracking system by effectively integrating a number of relevant research outcomes and techniques, and further refines the system through empirical comparisons and validations with several related algorithms.
