Parameter

**Table 1** Structure format description
Parameter	Type	Description
project_id	String	Project ID. For details about how to obtain the ID, see Obtaining the Project ID/Account Name/AK/SK.
image_url	String	Image URL. Currently, only the URL of an OBS bucket on Huawei Cloud is supported and FRS must have the permission to read data in the OBS bucket. For details about how to enable the read permission, see Service Authorization.
image_file	File	Local image file, whose size cannot exceed 8 MB. It is recommended that the image size be less than 1 MB. The request format is Multipart.
image_base64	String	Image data (Base64-encoded). Its requirements are as follows: The image size after Base64 encoding cannot exceed 8 MB. It is recommended that the image size be less than 1 MB. The image is in JPG, JPEG, BMP, or PNG format.
similarity	Double	Face similarity. The value ranges from 0 to 1. A larger value indicates a higher similarity degree. Generally, if the value is greater than 0.93, the faces in two images belong to one person.
face_set_name	String	Name of the facial image library. The value contains 1 to 64 characters, including letters, digits, hyphens (-), and underscores (_). Other special characters are not allowed.
face_set_capacity	Integer	Maximum capacity of a facial image library. The value is an integer multiple of 10000, for example, 30000. The default value is 100000, and the maximum value is 100000. You can create facial image libraries as you need.
face_id	String	Face ID returned by the system after a face is imported. The value consists of eight uppercase and lowercase letters that are randomly generated.
external_image_id	String	External image ID specified by the user. It is bound to the current image. If the user does not provide one, it is generated by the system. The ID contains 1 to 36 characters, including letters, digits, hyphens (-), and underscores (_). Other special characters are not allowed.
external_fields	JSON	Enters a value based on the customized data type. This field is defined when you create the facial image library. For details, see Customized Fields.
top_n	Integer	N faces returned that are most similar to the input one. The default value of N is 10. If the first five faces are returned, the value of variable N is 5. Value range: 1–1000
threshold	Double	Face similarity threshold. If the similarity degree of a face is lower than the threshold, the face is not returned. The value ranges from 0 to 1. The recommended value is 0.93. The default value is 0.
offset	Integer	Start number of data records to be read. The default value is 0.
limit	Integer	Number of records to be read. The default value is 5.
video_url	String	Video URL. Currently, only the URL of an OBS bucket on Huawei Cloud is supported and FRS must have the permission to read data in the OBS bucket. For details about how to enable the read permission, see Service Authorization. The video requirements are as follows: The video size after Base64 encoding cannot exceed 8 MB. The video duration must be 1 to 15 seconds. The recommended frame rate is 10 fps to 30 fps. The encapsulation format can be MP4, AVI, FLV, WEBM, ASF, or MOV. The video encoding format can be H.261, H.263, H.264, HEVC, VC-1, VP8, VP9, or WMV3.
video_file	File	Local video file. The request format is Multipart. The video requirements are as follows: The size of a video file cannot exceed 8 MB. It is recommended that the video file be compressed to 200 KB to 2 MB on the client. The video duration must be 1 to 15 seconds. The recommended frame rate is 10 fps to 30 fps. The encapsulation format can be MP4, AVI, FLV, WEBM, ASF, or MOV. The video encoding format can be H.261, H.263, H.264, HEVC, VC-1, VP8, VP9, or WMV3.
video_base64	String	Video data (Base64-encoded). Its requirements are as follows: The video size after Base64 encoding cannot exceed 8 MB. It is recommended that the video file be compressed to 200 KB to 2 MB on the client. The video duration must be 1 to 15 seconds. The recommended frame rate is 10 fps to 30 fps. The encapsulation format can be MP4, AVI, FLV, WEBM, ASF, or MOV. The video encoding format can be H.261, H.263, H.264, HEVC, VC-1, VP8, VP9, or WMV3.
actions	String	Action code sequence list. Actions are separated by commas (,). Currently, the following actions are supported: 1: Shake the head to the left. 2: Shake the head to the right. 3: Nod the head. 4: Mouth movement
action_time	String	String of the action time array. The length of the array is the same as the number of actions. Each item contains the start time and end time of the action in the corresponding sequence. The unit is the milliseconds from the video start time.
error_code	String	Error code returned after the API fails to be called.
error_msg	String	Error message returned after the API fails to be called.
