Detect API    文档中心/Detect API描述

传入图片进行人脸检测和人脸分析。
可以检测图片内的所有人脸，对于每个检测出的人脸，会给出其唯一标识 face_token，可用于后续的人脸分析、人脸比对等操作。对于正式 API Key，支持指定图片的某一区域进行人脸检测。
本 API 支持对检测到的人脸直接进行分析，获得人脸的关键点和各类属性信息。对于试用 API Key，最多只对人脸框面积最大的 5 个人脸进行分析，其他检测到的人脸可以使用 Face Analyze API 进行分析。对于正式 API Key，支持分析所有检测到的人脸。

关于 face_token

如果您需要将检测出的人脸用于后续的分析、比对等操作，建议将对应的 face_token 添加到 FaceSet 中。如果一个 face_token 在 72 小时内没有存放在任一 FaceSet 中，则该 face_token 将会失效。如果对同一张图片进行多次人脸检测，同一个人脸得到的 face_token 是不同的。

图片要求

图片格式：JPG(JPEG)，PNG
图片像素尺寸：最小 48*48 像素，最大 4096*4096 像素
图片文件大小：2 MB
最小人脸像素尺寸： 系统能够检测到的人脸框为一个正方形，正方形边长的最小值为图像短边长度的 48 分之一，最小值不低于 48 像素。 例如图片为 4096*3200 像素，则最小人脸像素尺寸为 66*66 像素。
