Hi, my first time here, I fell in love with ORFEO only a few weeks ago.

I am unsure on how to calculate the percentage each endmember has in the result of Hyperspectral unmixing. For an example RGB Pixel I have the values: [137.75, 123.70, 58.39] which with 4 endmembers gives me an abundance matrix of : [0.76, 0.03, -0.35, 0.92].

Am I right by assuming these are the coefficients of the linear equation that when multiplied with my endmembers results in the pixel value? How could I calculate a percentage of each endmember present in the pixel?

King reguards,
