Desert soil clay content estimation using reflectance spectroscopy preprocessed by fractional derivative.
Effective pretreatment of spectral reflectance is vital to model accuracy in soil parameter estimation. However, the classic integer derivative has some disadvantages, including spectral information loss and the introduction of high-frequency noise. In this paper, the fractional order derivative alg...
