Abstract

This paper presents a new approach to plant classification by using leaf edge feature combination with Morphological Transformations and defining key points on leaf edge with SIFT. There are three steps in the process. Image preprocessing, feature extraction, and image classification. In the image preprocessing step, image noise is removed with Morphological Transformations and leaf edge detect with Canny Edge Detection. The leaf edge is identified with SIFT, and the plant leaf feature was extracted by CNN according to the proposed method. The plant leaves are then classified by random forest. Experiments were performed on the PlantVillage dataset of 10 classes, 5 classes of healthy leaves, and 5 classes of diseased leaves. The results showed that the proposed method was able to classify plant species more accurately than using features based on leaf shape and texture. The proposed method has an accuracy of 95.62%.

叶缘特征结合形态变换和SIFT关键点的植物物种分类

提出了一种将叶缘特征与形态学变换相结合，利用SIFT定义叶缘关键点的植物分类新方法。这个过程有三个步骤。图像预处理，特征提取，图像分类。在图像预处理步骤中，使用形态学变换去除图像噪声，使用Canny边缘检测检测叶子边缘。利用SIFT对叶片边缘进行识别，并根据该方法对植物叶片特征进行CNN提取。然后用随机森林法对植物叶片进行分类。实验在PlantVillage的10类、5类健康叶片和5类患病叶片数据集上进行。结果表明，该方法能够比基于叶片形状和纹理的特征更准确地分类植物物种。该方法的准确率为95.62%。
