Facial Comparison

Capability Introduction

Landmark extraction, precise comparison

This API recognizes and extracts key facial features, performs high-precision comparisons of human faces, provides confidence scores, and determines whether the same person appears across different images. Cutting-edge facial comparison technology intelligently categorizes and manages photos. An intelligent image recognition algorithm ensures accurate facial recognition, and enables apps to provide an enhanced user experience.

Similarity comparison, identity authentication

This API performs high-precision facial comparisons, and can be applied in functions related face similarity, such as image management, face similarity comparisons, and identity authentication.

Automatic photo classification in gallery

Intelligently classifies photos in Gallery, based on the face comparison function.

Facial similarity comparisons

This function can be used to match a user's face with that of a similar-looking celebrity.



FaceComparator faceComparator= new FaceComparator(getApplicationContext());
Frame frame1 = new Frame();
Frame frame2 = new Frame();

JSONObject jsonObject = faceComparator.faceCompare(frame1, frame2, null);

1Can I call the faceCompare() method without calling the prepare() method of the API?

Yes, you can. The engine is started by default in the faceCompare() method. If the engine has already been started, it will not restart.

2When should I call the release() method?

The release() method will uninstall a model that has been loaded to the NPU chip. If the app is no longer using face detection, uninstall the model in a timely manner to free up resources.
