Non‐negative Independent Component Analysis and Its Application
Xianchuan Yu, Dan Hu, Jindong Xu · 2014
Some signals, such as image signals, do not satisfy the property of tending to zero. To solve this problem, we introduce the ordered nonnegative independent component analysis (ONICA) and integer wavelet transform ordered non-negative ICA (IWT-ONICA). Some practical applications of the algorithms for remote sensing images are presented at the end of this chapter.
