Unmixing methods on early and latewood of Spruce without background subtraction and based on 4 endmembers. Distribution maps given by all methods: from top to bottom VCA, NMF, MCR-ALS with no previous PCA and MCR-ALS with prior PCA. The images are scaled from minimum to maximum in each endmember. Black corresponds to the minimum intensity whereas white corresponds to the maximum
