Replacing the Red Band with the Red-SWIR Band (0.74<i>ρ</i><sub>red</sub>+0.26<i>ρ</i><sub>swir</sub>) Can Reduce the Sensitivity of Vegetation Indices to Soil Background

Replacing the Red Band with the Red-SWIR Band (0.74<i>ρ</i><sub>red</sub>+0.26<i>ρ</i><sub>swir</sub>) Can Reduce the Sensitivity of Vegetation Indices to Soil Background

Most vegetation indices (VIs) of remote sensing were designed based on the concept of soil-line, which represents a linear correlation between bare soil reflectance at the red and near-infrared (NIR) bands. Unfortunately, the soil-line can only suppress brightness variation, not color differences of...
