Abstract: Image classification can facilitate semantic retrieval and browsing of large-scale image databases. Existing approaches are usually based on extracting local or global low-level features such as color, edge, and texture from images. In this paper, we propose an image categorization method that characterizes the respective scene structures in images. 2D Spatial Frequency Map of an image, as well as the respective projection vector representations and principal component representations, are used to characterize the spatial structure of the image. Based on multiple similarity scores, we use a spectral clustering method and a maximal-spanning-tree-spectral-clustering method to generate image categories.
