Top Free Face Compare tools, APIs, and Open Source models

What is Face Compare API?

The Face Compare API, also called Face Similarity API, is a tool that enables app or system developers to integrate facial recognition and comparison functions. This API evaluates the closeness or similarity of two facial photographs based on facial traits. By applying robust algorithms and machine learning techniques, the Face Compare API can identify the resemblances and distinctions between two faces by analysing facial landmarks, patterns and attributes.

Here, you will compare two facial images to determine if they belong to the same person. The API requires two images: a reference image, such as the user's official ID, and a query image, like a selfie used for validation.

Top Open Source (Free) Face Compare models on the market

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of the best Face Similarity Open Source Models:

‍

1‍. Exadel

Exadel CompreFace is a cost-free and open-source facial recognition service that can be seamlessly integrated into any system without requiring prior knowledge in machine learning. It can be easily deployed using docker.

CompreFace furnishes a REST API for facial recognition, verification, and detection, as well as landmark detection, mask detection, head pose detection, and age and gender identification.

‍

2. DeepFaceLab

DeepFaceLab is a widely used open-source platform for creating deepfakes. It implements deep learning techniques to manipulate and exchange facial features. Although it primarily concentrates on producing deepfakes, it inherently entails face matching as a component of the procedure.

‍

3. face-comparison

AI Face comparison using FaceNet, compare two photos and see if they are the same person.

‍

4. Dlib

Dlib is a C++ library that provides a range of machine-learning tools, including facial recognition. It features a pre-trained face detection model that is well-regarded for its robustness, operating effectively in various orientations and lighting conditions.

Dlib also has integrated Python bindings, allowing it to be used with a variety of programming languages. You can also use this for face compare.

‍

5. MTCNN

The MTCNN (Multi-Task Cascaded Convolutional Networks) algorithm has transformed the face detection and recognition industry since its development in 2016. The technology uses a series of cascading neural networks to precisely and quickly detect, align, and extract facial features from digital images. You can also use this for face compare.

Cons of Using Open Source AI models

‍While open source models offer many advantages, they also come with some potential drawbacks and challenges. Here are some cons of using open source models:

‍

• Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear expenses related to hosting and server usage, especially when dealing with large or resource-intensive data sets.
• Lack of Support: Open source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
• Limited Documentation: Some open source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
• Security Concerns: Security vulnerabilities can exist in open source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open source models may need to monitor for security updates and patches actively.
• Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
