Top 10 Face Detection APIs

Top 10 Face Detection APIs

In this article, we will introduce our top 10 Face Detection APIs and how to choose and access the right engine according to your data.

What is Face Detection?

What does Face Detection do?

Face Detection API is a technology that enables computers to recognize and locate human faces within an image or video. This technology uses Computer Vision and Machine Learning algorithms to detect and identify faces, and then outputs information about the location, size, and associates characteristics such as age, gender, emotion to it.

Face Detection APIs can be integrated into other applications and systems and can be used for a variety of purposes, such as face recognition, face tracking, and facial expression analysis.

A brief history of Face Detection methods

The early pioneers of facial recognition were Woody Bledsoe, Helen Chan Wolf and Charles Bisson. In 1964 and 1965, Bledsoe, Wolf and Bisson began to work with computers to recognize the human face.

It wasn’t until the late 1980s that we saw further progress with the development of Facial Recognition software as a viable biometric for businesses. In 1988, Sirovich and Kirby began applying linear algebra to the problem of facial recognition.

In 1991, Turk and Pentland carried on the work of Sirovich and Kirby by discovering how to detect faces within an image which led to the earliest instances of automatic facial recognition. Face Recognition Grand Challenge (FRGC) was launched in 2006 in order to promote and advance face recognition technology designed to support existing face recognition efforts in the U.S. Government. The FRGC evaluated that the new algorithms were 10 times more accurate than the face recognition algorithms of 2002 and 100 times more accurate than those of 1995, showing the advancements of facial recognition technology over the past decade.

Since the 2010s, Facebook, Apple, Amazon, Google, and other big tech companies developed their own Face detection engines, and face detection is democratized in numerous fields.

Why choose Eden AI to manage your APIs

Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate Face Detection tasks in their cloud-based applications, without having to build their own solutions.‍

Eden AI offers multiple AI APIs on its platform amongst several technologies: Text-to-Speech, Language Detection, Sentiment analysis API, Summarization, Question Answering, Data Anonymization, Speech recognition, and so forth.

We want our users to have access to multiple Face Detection engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs:

Fallback provider is the ABCs

You need to set up a provider API that is requested if and only if the main Face Detection API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.

Performance optimization.

After the testing phase, you will be able to build a mapping of providers performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best Face Detection API.

Cost - Performance ratio optimization.

You can choose the cheapest Face Detection provider that performs well for your data.

Combine multiple AI APIs.

This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because Face Detection APIs will validate and invalidate each other for each piece of data.
