Kairos API vs OpenFace: What are the differences?

Kairos API: Kairos Human Analytics API. Commercial-grade emotion analysis, face detection and recognition engine provided as a public API Kairos takes the complexity out of facial recognition and emotion analysis so you can focus on building a great product.; OpenFace: Free and open source face recognition with deep neural networks. OpenFace is a Python and Torch implementation of face recognition with deep neural networks and is based on the CVPR 2015 paper FaceNet: A Unified Embedding for Face Recognition and Clustering by Florian Schroff, Dmitry Kalenichenko, and James Philbin at Google.

Kairos API and OpenFace can be primarily classified as "Facial Recognition" tools.

Some of the features offered by Kairos API are:

• Detect faces and face features within images
• Match faces against galleries of previously enrolled faces
• Analyze emotion of faces in still images and video

On the other hand, OpenFace provides the following key features:

• Detect faces with pre-trained models
• Transform faces for the neural network
• Use deep neural networks to reprsent or embed the face on a hypersphere

OpenFace is an open source tool with 12.2K GitHub stars and 2.99K GitHub forks. Here's a link to OpenFace's open source repository on GitHub.
