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 look at the places of maximum variation … 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 … See more 'Yale face database' is used here for training. This database contains many grayscale images of different face poses of many individuals . Here are the examples of some training images: Here are the examples of … See more Let X be a random vector with samples drawn from c classes: The scatter matrices S_{B} and S_{W} are calculated as: Fisher’s classic algorithm now looks for a projection W, that … See more WebEigenfaces is one of the simplest and oldest face recognition algorithms. It is relatively fast compared to other techniques for classifying faces The feature extractor must be retrained if large number of new faces are added to the system It is not accurate enough by itself and needs boosting methods for improvement. Easy peasy, right?
