The principle scheme of the registration-classification approach to shoot image segmentation. From left to right: higher contrast FLU images are automatically segmented and registered to VIS images. Due to motion artefacts, FLU/VIS co-registration is not exact which results in inclusion of marginal background regions. For separation of plant and marginal background regions supervised classification models trained for particular a case-scenario including camera view (top/side), plant type (arabidopsis, wheat, maize), developmental stages (juvenile, mid-stage, adult shoots) are applied
