WebThe motivation behind Fisherfaces is that since the training set is labeled with face identities, it will make more sense to use a class-specific linear method for both … 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 . When we look at a face we … See more So, we know that eigenfaces considers illumination an important feature of a face but it actually isn't. Considering these illuminations as an important feature it may discard other people's features considering them … See more 'Yale face database' is used here for training.
