Description
Leaf area is one of the fundamental variables to quantify plant growth and physiological function and is therefore widely used to characterize genotypes and their interaction with the environment. With the development of Plant Screen Mobile we provide a suitable smartphone solution for estimating proxies of leaf area and biomass in various imaging scenarios in the lab, greenhouse and in the field. This requires image segmentation of plant parts and background. Therefore the core of the application comprises different classification approaches. Beyond the estimation of projected leaf area the app can also be used to quantify color and shape parameters as well as to estimate the number of objects in an image (e.g. suitable for seed counting). A training procedure can be used to optimize the segmentation parametrization. The app is also available on Google Play Store.
