In the research of content-based image retrieval, visual signature based on region was attracted more attention. To get the signature based on region, the crucial step is image segmentation, and reliable image segmentation is also critical to get the image shape description. Unfortunately, it has been demonstrated that accurate image segmentation is still an open problem. So some strategies for dealing...
In this paper, we apply the principal component analysis (PCA) to extract significant image features and then incorporated them with the proposed two-phase fuzzy adaptive resonance theory neural network (Fuzzy-ART) for image content classification to overcome the gap between the low level features and high level semantic concepts. In general, Fuzzy-ART is an unsupervised clustering. Meanwhile, the...
This paper proposes an image semantic classification algorithm based on feature subspaces. It is implemented by SVM and AdaBoost algorithm. In every feature subspace, a SVM is trained. According to the error rate of every SVM, the integrating weight of feature subspace is determined, with which different subspace features are concatenated into a feature vector. Then AdaBoost algorithm is employed...
