Figure 5From: Invariant representation for spectral reflectance images and its applicationSegmentation results by using two alternative segmentation methods. (a) K-means [35] of the original spectral reflectance data; (b) PCA + Ncut [18] of the original spectral reflectance data; (c) K-means based on the proposed invariant representation; (d) PCA + Ncut based on the proposed invariant representation.Back to article page
