Objectives: A simple and efficient method is employed to extract feature vector from images and to reduce the dimension of data. Once the feature vectors are extracted, it can be used in face recognition module. Methods/Analysis: Principal Components Analysis (PCA) is used for face recognition technique for feature identification in large data sets and to highlight their similarities and differences is more essential step in face recognition. PCA is used as efficient tool in data analysis to reduce dimension and to obtain maximum variance of data. Findings: Experiment is conducted using Yale database B. The face images are formed with multiple factors on different lighting conditions, background interference, and face rotation etc. The experimental results on Yale database B are given to illustrate the proposed method. Conclusion/Application: A simple and effective feature extraction method is analyzed for face images and experimental results are shown.
