Abstract  The latent correlation between low-level features of different modalities is studied, and an optimizing algorithm is proposed to improve cluster quality of both image and audio datasets in the feature subspace. To speed up the convergence of query process, three active learning strategies in relevance feedback are incorporated. Thus, the condition probability of unlabeled samples around labeled examples is calculated. Experimental results show that overall cross-media retrieval results are encouraging, and the mutual retrieval between image and audio data can be effectively realized by the proposed algorithm.
