Fig. 2From: Root Hair Sizer: an algorithm for high throughput recovery of different root hair and root developmental parametersImage processing for root hairs thresholding and measurement. a Example of images before and after image processing to detect RH of M. truncatula root. Scale: 500 µm. b Comparison between automated detection of RHs (red line) and RHs on the original photo. Scale: 100 µm. c Image processing to measure and select maximal RH area in consecutive selections intervals. d RH length calculation using RH area in one selection. Magenta box corresponds to selection used to deduce RH lengthBack to article page
