Abstract：To reduce the gap between low-level image features and high-level semantic concept, support vector machine based relevance feedback draws more and more attentions. However, the information embedded in unlabeled samples is not utilized in that method. In order to exploit these information sufficiently, the transductive support vector machine (TSVM) is introduced into feedback process. Based on analyzing the characters of feature vector for TSVM, a color sparse feature is designed as the image description feature combined with the texture feature. Experimental results show that the proposed method is more discriminative than the feedback process using support vector machine (SVM), and TSVM obtains good results when applied to other fields.
