Embodiment Construction
[0035] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] A multi-biological feature fusion algorithm based on particle swarm optimization and typical correlation analysis, such as figure 1 shown, including the following steps:
[0037] Step 1: Image preprocessing: the original biometric image is reconstructed into a 32*32 image.
[0038] In this step, the original dataset image (ORL face image 112*92; finger vein image 60*128) needs to be reconstructed into a 32*32 image. The image reconstruction method is expressed as follows:
[0039] I = imread('IMG.jpg');
[0040] I=imresize(I,[32,32]);
[0041] Among them, IMG.jpg represents the original dataset image, and I represents the reconstructed image representation.
[0042] Step 2: Feature extraction, such as figure 2 As shown, through two convolution operations, feature selection operations and full connection operations, the preprocesse...
