Human Face is main part human body can be used for various purposes. Facial expressions, resulting from movements of the facial muscles, are the face changes in response to a person's internal emotional states, intentions, or social communications. Computer recognition of facial expressions has many important applications in intelligent human-computer interaction, awareness systems, surveillance and security, medical diagnosis, law enforcement, automated tutoring systems and many more. Face detection and Facial expression recognition system can be good source for express recognition activity. It can be used for important information, current state, and user behaviour and expression retrieval. Biometric area of research is well known activity of applications due to human interaction applications. As LBP convert any high definition file to greyscale, it leads to convert this file into low quality work. PCA suffers with the issue of involvement of least important facial part. The dark part of all such technique is lake of efficiency and accuracy due to consideration for least important facial feature during reorganization process. 2DPCA and E2DPCA algorithm can be used as the replacement algorithm to observed better accuracy and feature extraction. This work proposed to replace LBP with E2DPCA as the advance variant of PCA to get better level of performance. E2DPCA would remove least important part of face by estimating average value for individual classes than whose face. Subsequently, a modular approach will be used to obtain more perfection in extraction process. This work also proposed the use of .Euclidian distance measure for expression classifier. Yale algorithm for auto faces detection purpose. The best part of proposed work is evaluation on user images. The complete work will be evaluated on basis of JAFFE, Cohn-kanade and Self Images.
