Abstract—Face and Facial Expression Recognition is a broad
research area for its diversified applicability in different
applications from security, surveillance to medical diagnosis.
The main challenge in this area is to decrease the recognition
time as well as to increase the accuracy rate. In this paper, we
propose face identification system and facial expression
recognition system based on non-negative matrix factorization
(NMF). As facial parts are more prominent to express a
particular facial expression rather than whole faces and NMF
performs part based analysis, so we get a significant result for
face recognition. We test on CK+ and JAFFE dataset and we
find the face identification accuracy is nearly 99% and 96.24%.
But the facial expression recognition (FER) rate is not as good
as it required to be. We propose fusion based NMF method and
we name it as OEPA-NMF, where OEPA means Optimal
Expression specific Parts Accumulation. Our experimental
result shows that OEPA-NMF outperforms the predominant
Index Terms—Non-negative matrix factorization (NMF), facial expression recognition (FER), optimal expressionspecific parts accumulation (OEPA), face recognition (FR).
