DetectFace

public DetectFaceResponse DetectFace(DetectFaceRequest req)
                              throws TencentCloudSDKException

Application scenarios of this feature include: 1. [Creating](https://intl.cloud.tencent.com/document/product/867/45014?from_cn_redirect=1)/[Adding](https://intl.cloud.tencent.com/document/product/867/45016?from_cn_redirect=1) a person in a group: this is to ensure the quality of the face information to facilitate subsequent processing. 2. [Face search](https://intl.cloud.tencent.com/document/product/867/44994?from_cn_redirect=1): this is to ensure the quality of the input image to quickly find the corresponding person. 3. [Face verification](https://intl.cloud.tencent.com/document/product/867/44983?from_cn_redirect=1): this is to ensure the quality of the face information to avoid cases where the verification incorrectly fails. 4. Face fusion: this is to ensure the quality of the uploaded face images to improve the fusion effect. > - Please use the signature algorithm v3 to calculate the signature in the common parameters, that is, set the `SignatureMethod` parameter to `TC3-HMAC-SHA256`.

This API can be used to specify the face attributes that need to be computed and returned, which avoids ineffective computation and reduces time consumption. 2. This API supports more detailed attribute items and will continue providing new features in the future. Please use this API for corresponding face detection and attribute analysis. > - Please use the signature algorithm v3 to calculate the signature in the common parameters, that is, set the `SignatureMethod` parameter to `TC3-HMAC-SHA256`.

DetectLiveFace

public DetectLiveFaceResponse DetectLiveFace(DetectLiveFaceRequest req)
                                      throws TencentCloudSDKException

This API is used to detect the liveness of a face in a static image uploaded by a user. Compared with dynamic liveness detection, static liveness detection does not require moving lips, shaking head, or blinking for recognition. Image-based liveness detection is suitable for scenarios where the image is a selfie or the requirement for attack defense is not high. If you have a higher security requirement for liveness detection, please use [FaceID](https://intl.cloud.tencent.com/product/faceid?from_cn_redirect=1). > - The aspect ratio of the image should be close to 3:4 (width:height); otherwise, the score returned for the image will be meaningless. This API is suitable for selfie scenarios, and the score returned in other scenarios will be meaningless. > - During the process, please directly face the camera and keep a suitable distance to completely display your face in the recognition frame. During the recognition, keep your device still and fully show your face. You are advised to perform the detection in an environment with appropriate light and without filters. > - Please use the signature algorithm v3 to calculate the signature in the common parameters, that is, set the parameter `SignatureMethod` to `TC3-HMAC-SHA256`.

This API is used to judge whether a person in an image corresponds to a given `PersonId`. For more information on `PersonId`, please see [Group Management APIs](https://intl.cloud.tencent.com/document/product/867/45015?from_cn_redirect=1). This API fuses the features of all face images of a person; for example, if a person has 4 face images, it will fuse the features of the 4 face images and generate the summarized facial features of the person to make the person verification (i.e., judging whether the face image to be recognized is of a specified person) more accurate. The face verification APIs judge whether a person is someone specified whose information is stored in a group, and the "someone" may have multiple face images. By contrast, the face comparison APIs judge the similarity between two faces. > - Please use the signature algorithm v3 to calculate the signature in the common parameters, that is, set the `SignatureMethod` parameter to `TC3-HMAC-SHA256`. - This feature is available only to groups whose algorithm model version (`FaceModelVersion`) is 3.0.
