Abstract:

Crop diseases are one of the important factors on crop yield. At present, most researches use traditional machine learning and deep learning methods to identify and classify known diseases. However, this kind of model requires a lot of disease data, and it is not suitable for detection of new diseases. To overcome this problem, this work aims to detect the abnormal leaf diseases by using only the healthy leaf data sets as the training data. Specifically, a method of anomaly detection of crop leaf diseases based on k-means++clustering and image blocking is proposed. After image denoising, segmentation, interception and other preprocessing operations, the color moment features of the image are extracted, k-means++clustering is performed on the training set, and the comparison models are constructed and the threshold is set to determine whether the test set is abnormal or not. The datasets of potato, maize and apple leaves used in this experiment are downloaded from Kaggle website. By adjusting the cluster number and block number, the accuracy rate of potato, maize and apple leaf on test set is higher than 89%, 95% and 95%, respectively, and the missing alarm rates on maize and apple are 0.

Key words: leaf diseases, anomaly detection, image blocking
