[0037] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0038] Reference figure 1 , A supervised cross-modal hash retrieval method based on non-parametric Bayesian model, including the following steps:
[0039] Step 1) Obtain the original training data, and normalize the original training data to obtain the normalized training data X (t) , Where t represents the type of normalized training data, and t∈{1,2}, X (1) Represents the normalized image training data, X (2) Represents normalized text training data;
[0040] Step 2) Obtain the original test data, and normalize the original test data to obtain the normalized test data Y (t) , Where t represents the type of normalized test data, and t∈{1,2}, Y (1) Represents normalized image test data, Y (2) Indicates normalized text test data;
[0041] Step 3) For normalized training data X (t) Classification: According to the normalized training data X (t) The correspo...
