Neural networks, etc. can be applied.

A learning unit (not shown) separately provided in the access kiosk 10 or the management server 30 can acquire a learning model for a plurality of predetermined face images and depth data through learning. A learning process that receives face image and depth data as input data, and performs weight value tuning using forward inference and back propagation for the face image and the depth data for the corresponding face image. The learning model can be obtained through this.

In addition, in order to check whether the face image is the same in the process of collating the face image, feature points such as eyes, nose, mouth, and face outlines set in the face image area may be extracted and compared to determine whether the face image is identical.

In such a discrimination process, the more pre-registered images stored in the database are accumulated, the more accuracy can be improved through learning of the corresponding image, and as a result, face matching and authentication are performed accurately.

Furthermore, a neural network learning algorithm may be used to determine image restoration such as a photographic image for photo authentication or a case in which the identification card image is not clear, or forgery of a provided photo or identification card image.

In particular, by using Generative Adversarial Networks, a new image can be created or regenerated, so it can be used for damaged image restoration.

Unlike conventional deep learning networks, generative adversarial neural networks are structured with multiple deep neural networks, and require tens of times more computational load than existing deep neural network models to generate high-resolution images, but can provide excellent performance for image restoration. have.

In addition, the generative adversarial neural network is an unsupervised learning-based generation model that learns two networks adversarially with a generator and a discriminator, and input data is input to the generator to create a fake image similar to a real image. Can be learned to pay. The input data may be a noise value. The noise value can follow any probability distribution. For example, it may be data generated with Zero-Mean Gaussian.

The discriminator can learn to discriminate between the real image and the fake image generated by the generator. More specifically, it is possible to learn so that a high probability comes out when an actual image is input, and a probability decreases when a fake image is input. In other words, the discriminator can gradually learn to discriminate between real and fake images.

Furthermore, in the case of vision recognition cameras, AdaBoost, Support Vector Machine (SVM), Linear Disciminant Analysis (LDA), Principal Component Analusis : PCA) and other algorithms may be embedded.

All of these algorithmic techniques identify the area to be recognized based on the appearance, and detect the area around the face using a model trained by a set of captured images to be used for training, and overcome various surrounding constraints through training. As a result, the accuracy and reliability of face recognition can be improved.
