Abstract: This paper intents to develop an intelligent facial emotion recognition model by following four major processes like (a) Face detection (b) Feature extraction (c) Optimal feature selection and (d) Classification. In the face detection model, the face of the human is detected using the viola-Jones method. Then, the resultant face detected image is subjected to feature extraction via (a) LBP (b) DWT (c) GLCM. Further, the length of the features is large in size and hence it is essential to choose the most relevant features from the extracted image. The optimally chosen features are classified using NN. The outcome of NN portrays the type of emotions like Normal, disgust, fear, angry, smile, surprise or sad. As a novelty, this research work enhances the classification accuracy of the facial emotions by selecting the optimal features as well as optimizing the weight of NN. These both tasks are accomplished by hybridizing the concept of FF and JA together referred as MF-JFF. The resultant of NN is the accurate recognized facial emotion and the whole model is simply referred as MF-JFF-NN.
