Abstract :
Traditional spectrum image analysis method stays in pixel-level image analysis, so its analysis results are not accurate enough. Hyper-spectrum image has more spectrum bands, thus making it possible to analyze image in sub-pixel level. The method of hyper-spectrum data analysis contains linear model and nonlinear model. This article combines Approximate Hapke Model and single physical volume method (H-SPVM) for mix-pixel analyzing. We use H-SPVM on analyzing data from labs, and error rate of end-member extraction fell in 1%, error rate of mix-pixel analysis fell in 3%.
