1. INTRODUCTION: MOTIVATION AND AIM
The application of nonlinear manifold learning for hyperspec-
tral image analysis has been widely studied in last years [1,
4]. One of the main ingredients of these data reduction tech-
niques is the distance used to compare the spectral band im-
ages. By means of this distance the pairwise similarity matrix
is built and then, the matrix is used to explore the intrinsic
dimensionality of the hyperspectral image.
There are two main families of image distances which
have been considered in previous works: i) the distance be-
