Image Retrieval by Effective Description of Macro- and Micro-Content of Images

The visual words are a collection of local features of images, and generally used to represent image content. Considering the homogeneity of visual words, we design a visual vocabulary which contains macro-based and micro-based corresponding to feature points and key blocks visual words, respectively. We also apply the proposed visual vocabulary and description scheme to construct an image retrieving system. The performance evaluation of the method indicates that the proposed visual vocabulary achieves promising results.
