Microsoft Cognitive Services enable the developers to create robust AI algorithms in their applications. Cognitive APIs include vision, emotion, face, video, speech recognition, and more.
Overview of an Emotion API
Emotion API allows the applications to recognize the feelings showed by one or more people in a picture, then it returns a square box on the people's face. The Emotion API detects happiness, sadness, surprise, anger, fear, contempt, and neutral expressions on a face. When the API detects the emotions in the picture, then it returns an array of face entries & their feeling scores, ranked by faces with the rectangle in descending order. The Empty response ensures that there are no faces detected. This API takes a facial expression in a picture as an input and returns the confidence across a group of emotions for each look in the image.
The working conditions for Emotion API in our applications are,
The supported input picture formats consist of JPEG, PNG, GIF(Initial frame only), BMP. The image size must be no longer than 4MB. The trackable face size range is 36x36 to 4096x4096 pixels. Out of range pictures are not detected. For each picture, the maximum number of faces detected is 64, and the faces rankings are shown in descending order.
