EMOTION RECOGNITION APPARATUS USING FACIAL EXPRESSION AND EMOTION RECOGNITION METHOD USING THE SAME
First Claim
1. An emotion recognition apparatus using facial expressions comprising:
- a camera adapted to acquire a first video of an object corresponding to each of a plurality of emotions classified by a previously set reference;
a user input unit adapted to receive a plurality of first frames in the first video designated by a user;
a control unit adapted to recognize the face of the object contained in the plurality of first frames, extracting the facial elements of the object by using the recognized face, and extracting the variation patterns of the plurality of emotions by using the facial elements; and
a memory adapted to store the extracted variation patterns of the plurality of emotions, wherein if a second video of the object is acquired through the camera, a first variation pattern of the facial elements of the object contained in the second video is extracted, and the emotion corresponding to the variation pattern that is the same as the first variation pattern from the plurality of variations patterns stored in the memory is determined as the emotion of the object by means of the control unit.
