Summary of the image-based method for measuring imbibition and the data it produces. a Image of a kernel at the beginning and end of an imbibition trial (22 h). b Frequency histogram of the hue channel value in a three-color image of a kernel against the wet paper background. c Binary version of the image in a produced by applying a threshold to the histogram exemplified in b. d Example of a swelling curve produced by determining kernel area (a) at each 10-min time point, expressed as a fraction of the initial area, and a fit of the indicated equation to the raw data (dashed line). e Approximately 5000 fitted imbibition curves show the range of variation observed in this study
