摘要: 提出了一种改进的随机场模型SVM-CRF,它以支持向量机作为条件随机场的一阶势能项,结合了支持向量机和条件随机场的优点。采用AVIRIS高光谱遥感数据进行实验,对SVM-CRF模型进行了分析,结果表明,在分类精度上SVM-CRF优于支持向量机和传统条件随机场模型。Abstract: With there problems at hands,an improved random field,support vector machine conditional random field(SVM-CRF) was proposed.It uses SVM as its unary potential,combining the merits of SVM and CRF.Experiments using AVIRIS hyperspectral data as input were carried out,and SVM-CRF was analyzed extensively.Experimental results show that SVM-CRF is superior to SVM and classic CRF in terms of classification accuracies.
