Generalised nearest feature line for subspace learning
Yajun Pang, Yunhao Yuan, Xuelong Li · Electronics Letters · 2007
Nearest feature line (NFL) is a powerful tool in pattern recognition, which generalises the representational capacity of available prototypes by using linear interpolation and extrapolation between the feature points. NFL is generalised to subspace learning so that the obtained subspace has desirable discriminating ability. Experiments on face recognition demonstrate its effectiveness.
