Figure 1. Experimental workflow for quantifying waterlogging stress using RGB image-based i-traits.

Caption

a, Waterlogging treatment of 180 cultivated and wild chrysanthemum accessions at the seedling stage. b, Side- and top-view RGB images were collected at two time points: moderate waterlogging stress (T1) and severe waterlogging stress (T2). c, A procedure showing the image preprocessing, color correction and renaming of RGB images. d, A procedure showing image processing, binary image analysis and G, H, V component extraction of RGB images. e, A total of 10 morphological i-traits and 93 texture i-traits were extracted.
