Abstract:

Based on the idea of isomorphism, the image translation and rotation invariant feature could be formalized through the bispectrum. In order to expand the semantic scope of the results, a method called image retrieval based on diversity and invariant features (IRDIF) which can expand the diversity in search result has been applied in the semisupervised image retrieval. The item which has been visited will be set to be absorbing state, then the other items which are similar to the item of absorbing state will have smaller visiting probability. With this method, an experiment upon Corel database is conducted, and the final effect turns out to be quite satisfactory.

Key words:  semi-supervised learning, image retrieval, invariant features
