Abstract基于空间变换模型的目标跟踪问题常归结为非线性最小二乘优化问题,射影变换模型的高度非线性使得基于向量空间的优化算法倍显局限。通过李代数参数化将正则射影变换群局部线形化,在内蕴几何优化理论的框架下,提出一种射影变形目标跟踪算法。与基于向量空间的矩阵参数化的跟踪算法作对比实验,结果证实本文算法的可行性和高效性。
Other AbstractTarget tracking based on the space transformation model can usually be solved by dealing with another nonlinear least square optimization problem.The geometric optimization algorithm based on the vector space has more limitations for high nonlinearities of the projective transformation.The exponential mapping between the Lie group and its Lie algebra can make us to utilize the manifold structure to propose a more efficient projective target tracking method within the intrinsic geometric optimization framewo...
