Plant Leaf Area Estimation via Image Segmentation

In this paper, we propose a method to estimate plant leaf area using image segmentation. In the field of horticulture, destructive analysis is mainly made to measure leaf area, which is required for plant growth measurement. But it has the disadvantage that the plant cannot be used again after analysis. the proposed image based leaf area measurement is non-destructive, and it does not take much time compared with destructive analysis. Leaves in a plant image are first segmented, and then, their correlation to actual leaf area is analyzed. Experimental results show that we can easily predict actual leaf area from plant images.
