Shweta Patil, S.S.Katariya . Facial Expression Recognition using PCA Algorithm. Communications on Applied Electronics. 3, 3 ( October 2015), 22-24. DOI=10.5120/cae2015651904
Face is the primary focus for the identity of human. But while detecting the face one difficulty is there. How to deal with the variations in the facial expressions, lightening etc. in this paper we use the principal component analysis (PCA) algorithm for the detection of facial expression. First the eigen spaces are created with the help of eigen vectors and eigen values. With the help of this space eigen faces are created and with the help of PCA algorithm the most matching eigen face is selected. The databases of 30 persons are generated each person having 10 photographs with different expressions like happy, angry, sad, neutral etc. If any expression is not recognize then it consider as a neutral expression. The classifier used are based on Euclidian distance. Train and test databases are there but that should be in similar conditions such as distance, lightening, background etc. The results shows the accuracy of this algorithm.
