Figure 5

Classification schemes: (a) based on the mass, wingbeat frequency and length-to-width ratio; (b) based on the mass, wingbeat frequency, length-to-width ratio and body length. Note: The blue circles with numbers represent SVM classifiers, and the green circles with uppercase letters represent insect species. For a better figure arrangement, the subsequent classifiers after SVM 12 are placed on the right in (a), and a similar arrangement is used in (b).
