基于SVM和D-S证据理论的多特征融合杂草识别方法
Method of Multi-feature Fusion Based on SVM and D- S Evidence Theory in Weed Recognition
摘要
Abstract
According to the low accuracy and low stability of the single feature-based method for weed recognition, a multi-feature fusion method based on SVM and D - S evidence theory was proposed. Firstly, three types of visual features such as color, shape and texture were extracted from the plant leaves after a series of image processing. Then, the plants were classified according to each type of features utilizing SVM and the results were used as evidences to construct the basic probability assignment ( BPA ) . Finally, using D - S combination rule of evidence to achieve the decision fusion and giving final recognition results by classification thresholds. The experimental results show that the accuracy of multi-feature fusion method is over 97% and it has good performance on accuracy and stability compared to the single feature-based method in weed recognition.关键词
