Abstract
In this paper, we propose a modality-dependent cross-media retrieval approach under semi-supervised conditions. The approach utilizes both labeled samples and unlabeled ones to obtain two couples of projection matrices and uses feature distance to represent the semantic information of unlabeled samples in the optimization process, so as to fully utilize the data structural information. Different from supervised modality-dependent cross-media retrieval approaches which use labeled samples and fixed semantic information, the proposed approach makes full use of the global data distribution property and the semantic information of both labeled and unlabeled samples. Experiments on benchmark datasets show its superiority over the compared methods.
