PALO ALTO, Calif., March 02, 2017 -- Sighthound, Inc. today announced the release of a deeply learned emotion recognizer on its Sighthound Cloud API service. The emotion recognizer analyzes an image or video stream to find all faces and determine, for each face, the emotion along with an associated confidence level. Sighthound’s emotion recognizer has been trained to recognize seven different types of emotions.
Sighthound now has the world’s most accurate age detector, gender recognizer and emotion classifier, providing significantly more accurate results than the Microsoft Cognitive Services API.
