Hello, everyone. The meeting will answer your questions. Can Tencent face recognition take photos? can Tencent face recognition use photos? many people don't know this. Now let's take a look at it!

Answer:

1. Photos cannot be used; live detection (such as blinking) will be performed before face recognition, and photos will not pass in vivo detection, so photo unlocking will fail; multi-light source face recognition technology based on active near infrared image can overcome the influence of light change and achieve excellent recognition performance. The overall performance of the system in accuracy, stability and speed exceeds that of 3D image face recognition.

2. Can video be used for face recognition?

3. Video cannot be used in face recognition.

4. Face recognition needs knowledge-based representation, which is mainly based on the shape description of facial organs and the distance features between them to obtain feature data that are helpful to face classification. the feature components usually include Euclidean distance, curvature and angle between feature points.

5. The face consists of eyes, nose, mouth, chin and other parts. The geometric description and structural relationship of these parts can be used as important features of face recognition. These features are called geometric features.

6. Facial feature extraction: the features that can be used in face recognition system are usually divided into visual features, pixel statistical features, face image transformation coefficient features, face image algebraic features and so on. Facial feature extraction is aimed at some facial features.

This is the end of this article. I hope it will be helpful to all of you.
