PLANT CLASSIFICATION METHOD AND SYSTEM USING AUTORECOGNITION OF LEAF IMAGE

摘要

A plant classification method using automatic leaf image recognition according to the present invention comprises the following steps: obtaining a leaf image by an imaging device; extracting a distance parameter using the distance between the central point and the outline of the leaf in the leaf image; extracting a shape parameter using morphological features of the leaf in the leaf image; and determining the plant classification of the inputted leaf image by comparing the leaf image with recognition candidate leaf images based on the distance parameter and shape parameter. The distance parameter extraction step includes the following steps: detecting a leaf area in the leaf image; detecting the central point and the outline of the leaf in the leaf area; calculating distances from the central point of the leaf to all the pixels on the outline of the leaf; and extracting a distance parameter based on the calculated distances.
