Fig. 4From: High-throughput method for detection and quantification of lesions on leaf scale based on trypan blue staining and digital image analysisExamples of leaf lesion segmentation using the LiMu program. Images of leaves with a even and b uneven tissue clearing, acquired post-staining with trypan blue dye. c, d Labelled lesion segments from leaf images a and b. Uneven or incomplete clearing (b) can result in subsequent detection of false positive lesions (d) in poorly cleared leaf partsBack to article page
