Abstract: This paper introduced FSVM, which introjects fuzzy theory to SVM, achieves a classification system which classifies image layer by layer to affective semantic level by FSVM,and proposed one kind of image affective semantics classification method. The difficulty is to establish a mapping from image features to image affective semantics and how to select fitting membership function to test image semantic class. The experimental result shows that the system is simple,fast, effective, and so on, therefore our system is proved to be successful in promoting the image semantic classification to affective semantic level.
