Robust Visual Tracking via Fuzzy Kernel Representation
Zhiqiang Wen, Yongxin Long, Zhaoyi Peng · Journal of Computers · 2013
A r obust v isual k ernel t racking approach is presented for solving the problem of existing background pixels in object model. At first, after definition of fuzzy set on image is given, a fuzzy factor is embedded into object model to form the fuzzy kernel representation. Secondly, a fuzzy membership functions are generated by center-surround approach and log likelihood ratio of feature distributions. Thirdly, details about fuzzy kernel tracking algorithm is provided. After that, methods of parameter selection and performance evaluation for tracking algorithm are proposed. At last, a mass of experimental results are done to show our method can reduce the influence of the incomplete representation of object model via integrat ing both color features and background features.
