Image processing overview to assess tolerance and stress ratios under terminal drought stress (TDS) and well-watered (WW) conditions in wheat. a and d are cropped RGB images taken two weeks after drought stress induction under TDS and WW conditions, respectively. b and e are masked images in the Lab color space using defined function under TDS and WW conditions, respectively. c and f are masked images converted to binary format under TDS and WW conditions, respectively. Using this strategy, the black pixels represent non-dry tissues and the white pixels indicate dried tissues. The tolerance ratios were estimated as \(Tolerance \,ratio\, \left( {TOR} \right) = \left( {Black \,pixels} \right)/\left( {White \, pixels} \right)\) and the stress ratios as \(Stress\, ratio \, \left( {STR} \right) = \left( {White\, pixels} \right)/\left( {Black\, pixels} \right)\)
