Abstract :
We present two inversion algorithms to retrieve canopy structural parameters from multiangular and multispectral data sets. Correlation between bands is used as a priori knowledge quantitatively in our methods. Through detailed simulation and inversion, it is clear from the statistical analysis that these algorithms are stable to observation noise
