Webmaintaining discriminability. Our method Fisherfaces, a derivative of Fisher’s Linear Discriminant (FLD) [4], [5], maximizes the ratio of between-class scatter to that of within-class scatter. The Eigenface method is also based on linearly project-ing the image space to a low dimensional feature space [6], [7], [8].

WebThe technology of face recognition has become mature within these few years. System, using the face recognition, has become true in real life. In this paper, we will have a comparative study of three most recently methods for face recognition. One of the approach is eigenface, fisherfaces and other one is the elastic bunch graph matching.
Step 1: Retreive data Collection of data is done in form of face images . Collection can be done using photographs already saved or from a webcam. Face must be fully visible and must be facing forward.
