A Probabilistic Joint Sparse Regression Model for Semisupervised Hyperspectral Unmixing.
IEEE Geoscience and Remote Sensing Letters(2017)
摘要
Semisupervised hyperspectral unmixing finds the ratio of spectral library members in the mixture of hyperspectral pixels to find the proportion of pure materials in a natural scene. The two main challenges are noise in observed spectral vectors and high mutual coherence of spectral libraries. To tackle these challenges, we propose a probabilistic sparse regression method for linear hyperspectral u...
