Segmentation of Cereal Plant Images Using Level Set Methods – A Comparative Study

Mahmood R. Golzarian, Jinhai Cai, Ross A. Frick, and Stan J. Miklavcic

Abstract—In this paper we evaluate the quality of segmentation of plant images achieved by different level set methods commonly used in the literature. The plants of study are narrow-leaf cereal plants at different growth stages and the segmentation quality measure was considered to be the boundary, leaf tips, and axils. The results show that region-based level set methods can perform the segmentation of plants with high accuracy when the plants are at either early or mature stages of growth. The results also show that contour based level set algorithms are not applicable to the segmentation of narrow leaf plants because the front being computed does not advance to the high curvature features, such as sharp tips and axils. A typical image of a mature plant has isolated regions from the interlacing of leaves. Only region-based methods can perform the segmentation with good accuracy. Level set methods are sensitive to initialization and parameter selection.

Index Terms—Active Contour, Image Segmentation, Level Set, Narrow-Leaf plants.
