Embodiment Construction
[0052] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0053] figure 1 The block diagram of this system includes:
[0054] Step 1: Select the database of face images and preprocess the face images;
[0055] Step 2: Build a convolutional neural network model;
[0056] Step 3: training of convolutional neural network model zy_net;
[0057] Step 4: Output classification results.
[0058] figure 2 It is the network model structure of the present invention, which includes 5 layers of Mlp convolution layers, 4 layers of downsampling layers, two fully connected layers and a Softmax classification layer.
[0059] image 3 It is the preprocessed face image. The original image in the face data set has various forms, so in order to improve the recognition effect, it is necessary to preprocess the face image in the face database (face feature point detection, face alignment) , face clipping...
