We classify plant phenotypes into two categories: (a) holistic and (b) component-based. Holistic analysis considers the whole plant as a single object to quantify its geometrical shape, whereas component-based phenotyping analyzes the individual parts of a plant, i.e., leaves and stems. Holistic phenotypes are classified as primary or basic, and derived or advanced. Primary holistic phenotyping analysis measures the individual attributes of the basic geometrical shape, e.g., height of the bounding rectangle of a plant to quantify plant height, area of the convex-hull to quantify plant size. Derived holistic parameters combine two or more primary phenotypes for advanced plant phenotyping analysis.
