WebIn case one uses the normalized graph Laplacian, we show that spectral clustering usually converges to an intuitively appealing limit partition of the data space. We argue that in case of the unnormalized graph Laplacian, equally strong convergence results are difficult to obtain. Keywords Integral Operator Limit Operator Essential Spectrum WebHyperspectral images were acquired from a total of 1,680 Fusarium-infected wheat head samples over a wavelength range of 400-1000 nm. The principal component analysis was used to reduce dimension of the hyperspectral image. The central wavelengths at 660, 560 and 480 nm were combined into the RGB image and then transferred to YDbDr space.
