Two-phase Fuzzy-ART with Independent Component Analysis for Semantic Image Classification

Abstract-Analyzing the contents of an image and retrieving corresponding semantics are important in semantic-based image retrieval system. In this paper, we apply the independent component analysis (ICA) to extract significant image features and then incorporated it with the proposed Two-phase Fuzzy Adaptive Resonance Theory Neural Network (Fuzzy-ARTNN) for image content classification. In general, Fuzzy-ARTNN is an unsupervised classifier. Meanwhile, the training patterns in image content analysis are labeled with corresponding categories. This category information is useful for supervised learning. Thus, a supervised learning mechanism is added to label the category of the cluster centers derived by the Fuzzy-ART. The experimental results show that the proposed method has a high accuracy for semantic-based photograph analysis, and the result of photograph analysis is similar to perception of the human eyes.
