Quantitative Estimation of Tobacco Copper Ion Content from Hyperspectral Data by Inverting a Modified Radiative Transfer Model: Algorithm and Preliminary Validation

<div>Comparison between the measured and estimated values of water contents. (a) Scatter plot of the measured and estimated values of water contents. (b) Relative errors of water contents. The horizontal axis represents the sample number, while the vertical axis represents the relative error multiplied by a factor of 100.</div>
