Summary:A method of leaf recognition for identifying the species of a leaf is disclosed. The method comprises: an image accessing step, a pre-processing step, a features extracting step and a comparison step. The image accessing step accesses a input image containing a input leaf. The pre-processing step processes the input image with gray scaling and thresholding operations to generate a binary image, and calculates the centroid of the binary image to isolate the input leaf. The features extracting step extracts features of the input leaf, where the features includes at least one clear feature and at least one fuzzy feature. The comparison step uses the clear features to classify the leaves; then locates all the species of a database with the same clear feature classification of the input leaf; further compares the difference between the fuzzy features of the input leaf and the fuzzy features of the above mentioned species. Accordingly, the species that the input leaf belongs to can be recognized.
