Abstract: | At first,the within-scatter and between-scatter matrices are calculated respectively,and the ’minus’ form objective function is obtained.Secondly,the projection matrix is obtained by calculating the eigenvector.Finally,the plant taxonomy experiment if carriedout based on real plant leaf database.Results show that the proposed method is effective and feasible for plant taxonomy |
