与传统稀疏表示模型不同,该文提出一个基于典型相关性分析的稀疏表示模型,此模型首先使用两种特征来表征粒子观测向量,然后对两种观测向量的子空间投影结果进行稀疏建模。 |
Different from traditional sparse representation model, a canonical correlation analysis based sparse representation model is proposed in this paper. The proposed model first uses two kinds of features to represent the particle observations, then, the projections of particle observations are used to build the sparse representation model. |
