Abstract: This paper presents a methodology for identification and classification of images of the medicinal plants based on level set segmentation. The medicinal plants are identified using structural features, namely, height, shape, size of leafy part, flowers, fruits, and branching patterns. In this work, the level sets are used for segmentation of images of medicinal plants. The two segments, namely, leafy part (canopy) and stem, are obtained. The geometrical ratios of length to width of leafy and stem parts of images are used as features. The classification of images of medicinal plants into herbs, shrubs and trees using minimum distance, neural network and SVM classifiers is performed. The experiments are carried on 400 images of medicinal plants of different classes, such as Calotropis gigantea, Aloe vera, Catharantus roseus, Carica Papaya, Azadirachita indica and Cocos nucifera. The classification accuracies obtained by different classifiers are compared. It is observed that the combination of level set segmentation and SVM classifier yielded better classification results. The knowledge of these medicinal plants is useful for practitioners of Ayurveda system of medicine, botanists and common man for home remedies.
