Abstract  Hashing methods possess advantages of low storage cost and fast query speed. However, most of the current hashing methods are designed to handle simple binary similarity rather than the complex multilevel semantic structure of the images associated with multiple labels. In this paper, a multi-label contractive hashing method(MLCH) is proposed to preserve the multilevel semantic similarity of multi-label images. In particular, the supervising information of attributes is proposed to help the training of the model and adopt an optimized selection algorithm to select training samples. Meanwhile, a contractive constrain term is added to the loss function to improve the quality of the generated binary codes. The proposed approach is evaluated on CelebA and PubFig databases, and the experimental results demonstrate its superiority over several state-of-the-art hashing methods on the task of large-scale image retrieval.
