It is different from general tracking models, such as probabilistic or neural network model. 我们再将一些可能改进的方法加入到影像子空间模型中。
Based on input-output data, state space models are directly identified by the SMI methods combined with the system theory, linear algebra and statistics. 这类方法综合了系统理论，线性代数和统计学三方面的思想，其特点是直接由输入输出数据辨识系统的状态空间模型，因而非常适合多变量系统辨识。
