Example cropped images generated using LAMINA in a range of species. A Three example Artemisia annua leaves. Some regions are incorrectly identified as cavities, however the perimeter is correctly identified. B Example image from [21]. Serration detection pixel threshold = 50. C Example image from [23]. D Example Populus leaves from Umeå Plant Science Centre 2006 Calendar. E Example Image containing a range of leaves from common European tree species with contrasting leaf shapes. F Example use of serration detection to measure lobes in a senescing maple leaf. Serration detection pixel threshold = 75. G An example set of Arabidopsis thaliana leaves representing a developmental series. All images were analysed using the Greedy search threshold setting.
