[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.
[0053] Such as figure 1 The shown multimodal biological feature fusion recognition method based on tag discrimination correlation analysis includes the following steps:
[0054] Step 1: Input the feature vector of the multimodal image;
[0055] Step 2: For different biological features, the category label and biological feature are fused to obtain a feature set with category label information;
[0056] Step 3: Fuse the different modal feature sets obtained in step 2, and use the maximum correlation between the two to establish a criterion function to obtain the projection vector, and then obtain the fused feature set;
[0057] Step 4: The feature sets obtained in step 3 are respectively used for parallel fusion and serial fusion, and classification and recognition are performed by the nearest neighbor method.
[0058] The category labels and fe...
