WebThe hyperpca and hypermnf functions reduce the spectral dimensionality of the data cube by using the PCA and MNF transforms respectively. You can use the pixel spectra derived from the reduced data cube for hyperspectral data analysis. Spectral Unmixing. In a hyperspectral image, the intensity values recorded at each ... WebHyperspectral data examined like an. % in the image. Therefore, a single element of such an image will be. % (i.e. 2D matrix) is defined as M (m·n)×p of dimension (m· n)×p. % accessed using M:,j . Notice the multi-element notation is consistent. % with MatlabTM this is intentional. % throughout this code. % M Data matrix.
