Combination of Chain Code and Leaf Morphology Approach for Plant Identification

This research will identify plants based on 16 basic leaf shapes. It uses 3 leaf datasets, namely Flavia, Folio and Swedish dataset. The researcher used 12 features that consist of 5 basic geometry features and 7 digital morphological features. Geometry features include physiology length, physiology width, diameter, area, and leaf perimeter while digital morphological features involve smooth factors, aspect ratio, circularity, rectangularity, narrow factor, the ratio between perimeter and diameter combined with chain code in determining the ratio between perimeters and lastly, the length and width of physiology. Accuracy result showed that 98.48% of the plants were correctly identified.
