Abstract: Facial recognition is the process of identi?cation of humans by the beyond wildest dreams characteristics of their Faces. Face recognition technology is the end intrusive and fastest bio-metric technology to identify the human face. With increasing money in the bank needs and by all of advancement in technology extracting taste has become roughly simpler. Authentication by passwords are not secure, so this technology are much more important as for upcoming security and safety measures. Many technologies have been developed for finding the best possible ways to describe the face descriptors and finding the face from available database of images. In this Paper we have discussed some understanding about Facial Recognition and differences between two algorithms which are used for facial description, these are PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis).
Keywords: Face Recognition; PCA Algorithm; LDA Algorithm; Image Processing.
