| Summary: | 碩士 === 國立交通大學 === 電控工程研究所 === 101 === In this thesis, a target model updating method based on 3-D mean-shift tracking
algorithm is proposed. The algorithm is aimed at reducing the influence of complex
and dynamic background. It uses principal component analysis to estimate the size and
rotation of the target in 3-Dimensions. With the 3-D spatial information and new target
model updating method, this algorithm outperforms other target model updating
methods such as traditional Mean-Shift and 3-D Mean-Shift. The method consists of a
set of rules to construct online template database. These results in a better and faster
tracking process. In particular, when target rotates drastically, it gives a more accurate
and stable result compared to other methods that only update the target model.
