A Rapid Intelligent Screening of a Three-Band Index for Estimating Soil Copper Content

A Rapid Intelligent Screening of a Three-Band Index for Estimating Soil Copper Content

Research has widely validated three-band spectral index as a simple, valid, and highly accurate method of estimating the copper content of soil. However, selecting the best band combination from hundreds of thousands, even millions of candidate combinations in hyperspectral data, is a very complicat...
