A Modified Feature Trained Discriminative Classifier For Facial Expression Recognition

[Full Text]



Rakesh Sharma, Sukhjinder Kaur



Facial Expression Recognition, Local Phase Quantization, Local Direction Pattern, Support Vector Machine



Recognition of the human facial feature using technology is being emerged widely. In the recent times, many image processing techniques have been developed with the different approaches in order to recognize the expressions or human emotions from the image. This paper has presented a novel approach which used different components of the human face that includes pair of eyes, and mouth as the essential parameters to recognize the gesture or the expression of the face. The features are extracted using LDP (Local Direction Pattern) and LPQ (Local Phase Quantization) techniques of feature extraction. These techniques outweigh the techniques used in the traditional work (LBP and LTP). The complexity is reduced and Support vector machine is deployed for classification and recognition of the particular tasks. Simulation is performed using MATLAB and results demonstrated that the proposed system to recognize facial expressions has less complexity and more efficiency as compared to the traditional FER.
