摘要
This study clarifies the implicit potential deficiency caused by the sparse cardinality parameter k in Rong et al. (2014). In addition, k = beta x W x M x N (0.9 <= beta < 1) is suggested to avert this potential deficiency, where beta is a ratio controlling the amount of sparse cardinality, W is the number of multispectral bands and M x N is the size of panchromatic image. With the choice of k suggested in this study, the low rank matrix L and sparse matrix S obtained by Go Decomposition (Zhou and Tao 2011) can be iteratively optimized and solved. Thus, instead of choosing k as W x M x N in Rong et al. (2014), the potential deficiency that L is directly obtained as an analytic solution can be averted.
