How to Implement Facial Recognition in Your App or Software?

Before you invest in facial recognition app development, it is essential that you understand the concept completely. What would you like to create and how should it work? Once you have it figured out, here are three ways to implement FRT in your mobile app:

facial recognition app development ways

1. Use Native Face Detection APIs

When you develop a mobile app, you develop it for iOS, Android, or both. These platforms offer their own APIs to help you integrate facial recognition features into the app.

Even though the functionality these APIs provide will be limited, you can reduce the cost of face recognition app development NYC by many folds using these options. You just need to integrate the API into your app and ensure reliable picture detection and recognition features.

The most important advantage of using native APIs is that they are optimized for lots of devices and are also improved using hardware acceleration components. For example, Vision API is an API by Apple for things related to computer vision. It has detectors that let you find faces, text, and barcodes.

Native Face Detection APIs
Pros Cons
Easy to integrate Lack features
Affordable Not many options available
Optimized for most devices
Requires no extra time & effort

2. Consider OpenCV Library

This is the commonly used library to develop facial recognition apps. It helps implement computer vision as well as ML in the applications. Basically, OpenCV is an object detection platform that helps detect all types of objects and also works well around several algorithms. This library works well for facial recognition and detection in many cases.

Initially, OpenCV was built for the standardization of the general interface of computer vision and for the invention of new models. Its main advantage is that it is free to use. However, its integration with mobile applications is a bit complex, especially when it comes to face detection in Android. It requires extensive knowledge.

OpenCV (Haar-Cascade)
Pros Cons
Available free of cost Unable to detect side faces
Fast and capable of running in real-time (written in C/C++) Performs poorly in different poses & lighting conditions
Small model size around 400 KB and 10 MB for DLFD Hard to integrate with mobile apps
Utilizes modern deep learning algorithms Exists as SDK only

3. Choose a Third-Party Solution

The market is full of various offers to make the development process smooth and highly convenient. You can use third-party services like Microsoft Face API, Google’s Cloud Vision API, Amazon Rekognition, Kairos, and many others to integrate facial recognition in your app or use FTR to improve your business processes. Usually, these services are paid but offer amazing functionality by recognizing not just faces but emotions, ethnicity, and many other things.
