In this paper, we propose and compare two different approaches for quantification of skin hemoglobin and melanin on multi-spectral images. The first method is based on non-negative matrix factorization (NMF) with multiplicative update algorithm. The second method is a Beer-Lambert law based model-fitting technique. Quantitative evaluation through graph-cut segmentation on melanoma indicates that model-fitting method obtains more accurate quantification than NMF.
