How To Use Face Recognition In App Development Using Deep Learning?

As humans, recognizing the face that comes normally but thinks of a kid who is still fattening and capturing to identify people. If you listen and realize that children confuse people who have the same facial structures like eyebrows or lengthy beards or broad chin. But a machine trained like child perspectives with deep learning technologies. Before going into how facial recognition can be work into an app, let’s discuss how the technology worked.

Face recognition

The computer algorithm of facial recognition application is a bit like human visual recognition. But if people store image data in a brain and automatically retrieve image data once needed, computers should request to collect data from a database and match them to recognize a human face.

Using face recognition


Companies are training the deep learning algorithms to recognize this fraud detection, decrease the need for traditional usernames and passwords, and enhance the ability to differentiate between a human face and an image dataset.

Never interacted hardware

Technology has enabled a large number of new biometric identification systems that use fingerprints, iris scans, wrist vein scans, speech recognition, and face recognition. But when it comes to the potential for privacy invasion, however, these different methods are done with applications. So it can’t interact with hardware.

Easy integration

The main features of the images are unidirectional radiation patterns, low cost, lightweight, low profile, simple construction and compatibility, and ease of integration with facial detection.

Deep learning

Deep learning is a part of a machine learning technique that teaches the machines to do what comes naturally to humans: that learn by the real world. Deep learning is a subset technology behind driverless cars, achieve them to recognize a stop sign, and more. It is the key control in customer devices like phones, tablets, TVs, smartwatches, and hands-free speakers. Deep learning is one of the most gigantic ways to improve face recognition technology. The approach is to extract face embeddings from images with faces.

Deep learning algorithms for face recognition app development

The data faceprint that stored via facial traits that are compared by the face recognition application using a deep learning process. It makes an analogy between the real-time data capture and the stored database to identify an individual. There are four main concepts subjected to deep learning for facial recognition detection of facial features, alignment, feature extraction, and recognition.

The process involved in face recognition

1. Face detection

 Identify the human face in the digital images, that locate one or more faces and crop the image data and detect a visual scene.

2. Face alignment

Normalize the face to be standard with the storage device, such as geometry and photometric. It will be determined to face shape such as eye, noise.

3. Feature extraction

It’s a type of dimensionality reduction where a large number of pixels of the image are efficient that to be entitled in such a way that fascinating parts of the image are captured effectively. Extract features from the face that can be used for the recognition task.

4. Face recognition

Uses the Dlib tool to calculate the dimensional descriptor vector of face features. Whenever a vector is calculated, it is compared with the multiple referential face images by analyzing the euclidean distance to each feature vector of each Person in the database and finding an image.

Applications of facial recognition

Hardware security

With the increase in dependency on smartphones, computers for confidential work it is very significant to secure the hardware. The 3D facial recognition biometric can be used to elevate the level of phone and computer security.

Criminal identification

This type of identification is constrained as most criminals nowadays getting cleverer not to leave their thumbprint on the screen. This will help the law fulfilments to detect or recognize the suspect of the case if no thumbprint present on the scene. The results show that the exact percentage of input photos can be matched with the template data.

Mask detection

In this scenario, we are wearing masks, so cameras can now recognize faces that are covered with masks. Using the deep learning algorithm based on convolutional neural networks, cameras can now recognize faces that are covered with masks. It utilizes such algorithms as face-eye-based multi-granularity and periocular recognition models to achieve facial mask recognition.

Airport security

Places like international airports are more likely to have the movement of people of interest trying to evade enforcement authorities. This presents a security challenge as well as an opportunity to catch criminals by scanning their faces.

Emotions recognition

Recognition on tracking the movements of a face through the camera, the emotion recognition technology categorizes human emotions. Most work has been conducted on the recognition of facial expressions from video, spoken expressions from audio, written expressions from the text, and find them. The deep learning algorithm identifies points of a human face, that detect a neutral facial expression to measures the deviations of facial expressions that are recognizing more positive or negative ones.

Face recognition application used the work under constrained terms and conditions. These applications work much better with frontal mug-shot images with constant lighting. It will expect to see continued implementation of facial recognition technology across industries, with certain banking sectors, like securable sectors that are leading the race when it comes to innovation achievements.
