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. Step 2: Image Processing a) Preprocessing stage : Getting images using camera or saved images and conversion … See more This algorithm follows the concept that all the parts of face are not equally important or useful for face recognition .
