Embodiment 1
[0045] Such as Figure 1 to Figure 3 As shown, a face feature extraction system based on FECNN, including face preprocessing module 1, FECNN (FECNN is Fast and Effective Convolutional Neural Networks, is an efficient convolutional neural network) module 2, feature extraction module 3 and feature ratio for module 4;
[0046] Described human face preprocessing module 1 is used for carrying out human face detection to human face pictures, and the detected human face image is cut out, and the human face key point is located on the human face image, and then the human face key point is combined with Align face images;
[0047] The FECNN module 2 is used to build the FECNN framework for feature extraction, and uses the training library sample face to train the FECNN framework until the FECNN framework converges to obtain the FECNN parameter model;
[0048] The feature extraction module 3 is used to extract the FECNN to extract the network parameter model, send the face key points ...
Embodiment 2
[0066] Such as Figure 4 Shown, a face feature extraction method based on FECNN, including the following steps:
[0067] Step S1. Face preprocessing module 1 performs face detection on the face picture, and cuts the detected face image, locates the key points of the face on the face image, and then compares the key points of the face with the face The images are aligned; the FECNN module 2 builds the FECNN framework for feature extraction, and uses the training library sample face to train the FECNN framework until the FECNN framework converges to obtain the FECNN parameter model;
[0068] Step S2. The feature extraction module 3 extracts the FECNN to extract the network parameter model, sends the key points of the face and the face image into the FECNN parameter model for feature extraction, and outputs the face features;
[0069] Step S3. The feature comparison module 4 uses the cosine distance to calculate the face features. When the calculated distance is greater than the...
