情感 API ^预览

分析面部，检测一系列情感，并对应用的响应进行个性化设置。

识别图像中的情感

情感 API 以图像中的面部表情作为输入，并使用人脸 API 返回图像中每张脸对应一组情感中的可信度，以及面部的边界框。如果用户已调用人脸 API，则可将面部矩形作为可选输入提交。

可检测到的情感包括愤怒、蔑视、厌恶、恐惧、幸福、中立、悲伤和惊喜。可以认为这些情感跨越了文化界限，通常由特定的面部表情传达。

识别视频中的情感

The Emotion API for Video recognizes the facial expressions of people in a video, and returns a summary of their emotions. You can use this API to track how a person or a crowd responds to your content over time. The emotions detected are anger, contempt, disgust, fear, happiness, neutral, sadness, and surprise.

Recognize emotions in near real-time by extracting frames of a video and then sending those frames to the API calls of your choice. Get results faster and quickly start coding using our sample on GitHub.
