| Abstract(in English) | We propose a recognition method of trees using leaf images. We take two leaf images of surface and underside from a cut leaf on the white sheet. At this time, a marker is put on the background. At first, we extract the object region using a graph cuts algorithm. Secondly we define 25 features, and these features are fed to a nearest neighbor method. We collected 20 pairs of pictures from 50 trees in the fields around our campus. We found the underside image is better than the surface image. We obtained the recognition rates of 80.5% in the 1st candidate and 96.2% in the 5th candidates with 13 features. Moreover, we found the actual size improves 5% of recognition rate. |
