Facial emotional recognition apparatus for Identify Emotion and method thereof

摘要

The present invention relates to a facial emotion recognition apparatus for distinguishing emotion from an input facial image and a method thereof. According to the present invention, the facial emotion recognition apparatus comprises: a facial feature extraction unit receiving the facial image from which the emotion is distinguished, extracting features of the entire facial image from the inputted facial image, and transferring information about two high-ranking emotions among acquired six emotions from the extracted features; a geometric variance extraction unit comparing feature points assigned to the inputted facial image with feature points assigned to a default facial image with respect to the same person to extract a coordinate difference and applying a coordinate difference value to a CNN algorithm to calculate vector values of the two high-ranking emotions; and an emotion classification unit assigning weight to an emotion recognition value extracted from the facial feature extraction unit and the vector values calculated in the geometric variance extraction unit to classify the emotion having the highest value among calculated result values as a final emotion. Accordingly, the facial emotion recognition apparatus corrects an emotion recognition error frequently generated from two high-ranking emotions acquired through an existing algorithm and assigns the weight to the emotion recognition value extracted from the facial features and the vector values calculated from geometric variances to calculate a result value, thereby providing an effect of determining the final emotion with increased correctness.
