Novel X-ray imaging and segmentation of root structures

Purpose - This paper seeks to present a novel X-ray system and associated image segmentation algorithm for imaging the below-ground root structures of plants. Design/methodology/approach - A matched filter design for segmenting the important root structures from the background clutter in the X-ray images was presented. Findings - The feasibility of root imaging and the applicability of matched filters to this problem domain have been demonstrated. Originality/value - This research offers a novel approach over existing methods for in situ monitoring of root structures through the application of matched filters for image segmentation.
