Abstract: Nowadays, more and more digital images are available. How to find a required image quickly for a user has become harder and harder. Acquiring semantic information of images and realising automatic image annotation is an effective technology to improve the performance of image retrieval. This paper presents a method of sentiment annotation of natural images based on fuzzy theory. The method describes image emotional level by computing fuzzy membership degree, uses BP neural network to implement it and solves semantic ambiguity on automatic image annotation. Using 967 natural images downloaded by Baidu photo channel to train and test, experiments achieved good effect compared with manual annotation results. The proposed method can lay a good foundation for automatic semantic annotation of more types of images.
