Face Recognition Using PCA & Neural Network
The face recognition scheme based on neural network and PCA technique for the detection of the persons. the author have used the PCA technique which involves a mathematical method that transforms a number of possibly correlated variables into a smaller number of uncorrelated variables called principal components. Pre-processing stage - In this stage the images are made zero-mean and unit-variance. dimensionality reduction stage: Program Component Analysis (PCA) - Input data is reduced to a lower dimension to facilitate classification.
