(a) Estimated \(\sigma\) through spectral bands with a dashed red line denoting the adopted threshold for selection of relevant spectral bands. \(\sigma\)s values are colored blue/red color to specify if the corresponding spectral bands are kept or disregarded from further analysis. The spectral bands which correspond to the \(\sigma\)s colored in green are kept since they provide useful information for sepal segmentation (b) Spectral response of a pixel belonging to a sepal marked with blue, red and green colors for correspondence with the estimated \(\sigma\)s in the graph on the left.
