Fig. 9

The relative error of the fractional vegetation cover measured using different algorithms under the solar noon scenario. Fun01 is based on the combination of \(R/G\), \(B/G\) and \(2G-R-B\). Fun02 is the decision tree algorithm based on RGB color. Fun03 used the excess green and red indices to recognize the plants in the image. Fun04 uses the excess green index and the Otsu algorithm to identify the plants in the image
