Abstract

The sun-target-sensor angle can change during aerial remote sensing. In an attempt to compensate BRDF eﬀects in multi-angular hyperspectral images, the Semi-Supervised Manifold Alignment (SSMA) algorithm pulls data from similar classes together and pushes data from diﬀerent classes apart. SSMA uses Laplacian Eigenmaps (LE) to preserve the original geometric structure of each local data set independently. In this paper, we replace LE with Spatial-Spectral Schoedinger Eigenmaps (SSSE) which was designed to be a semisupervised enhancement to the to extend the SSMA methodology and improve classiﬁcation of multi-angular hyperspectral images captured over Hog Island in the Virginia Coast Reserve.
