A tetrahedron-based endmember selection approach for urban impervious surface mapping.

PLoS ONE, 2014
The pixel purity index (PPI) and two-dimensional (2-D) scatter plots are two popular techniques for endmember extraction in remote sensing spectral mixture analysis, yet both suffer from one major drawback, that is, the selection of a final set of ...
