Fig. 11From: A high-throughput stereo-imaging system for quantifying rape leaf traits during the seedling stageThe primary procedure for individual leaf traits extract. a The original rape leaf image. b The selected single rape leaf region. c Select two points on the image. The first point is the intersective region of stem and leaf and the second point is used to decide the direction of rotation. d The rotated oilseed rape leaf image. e Using normalized EG and ER to segment the leaf region. f Remove the petiole region and connected region screeningBack to article page
