Embodiment Construction
[0031] A cross-modal hash learning method based on anchor graphs, which establishes the characteristics of n objects in image mode and text mode as with in, with represent the feature vectors of the i-th object in image mode and text mode respectively, i=1,2,...,n,d 1 and d 2 represent the dimensions of the feature vectors of the image modality and the text modality respectively; at the same time, it is assumed that the feature vectors of the image modality and the text modality are preprocessed by zero centralization, that is, satisfy suppose with are the adjacency matrices of image modality and text modality samples respectively; matrix A (1) elements in and matrix A (2) elements in Represents the similarity between the i-th sample and the j-th sample in the image modality and the text modality respectively; suppose S∈{0,1} n×n is the semantic correlation matrix between samples in two modalities, where S ij Indicates the semantic correlation between the i...
