Principal Component Image Interpretation - A Logical and Statistical Approach
Principal Component Analysis, Eigenvalue, Eigenvector, Component Loading Factor.
Principal component analysis a multivariate statistical data analysis algorithm widely used as a dimensionality reduction algorithm in image processing task. In remote sensing data analysis, PCA used as a spectral enhancement pre-processing algorithm to reduce higher dimension space to lower dimension space with preservation of all the information in original variables. This paper provides a lucid approach to analyse and interpret PC images using statistical and logical approach. It also describe the dependency of the tonal variation of pixel vector of PCs image with magnitude and sign (negative or positive) of the coefficient of eigenvector and pixel value in original multi-spectral bands.
